Abstract
This report discussed the effect of workstation design, assembly design, jig design and working posture on the assembly of plugs. Two different designs of jig (vertical and rectangular) and two sets of assembly line design (one and two operators) and two set of workstations design (sitting and standing) were studied to observe their effects to productivity. Design of
Experiments 23 with two levels of each factor is used to conduct an experiment for obtaining the most productive jig and assembly line design. Two groups of workers were employed to assemble the plug in 8 different ways. Number of replication is 32 for each setting and total of electric plugs produced by each group is 256 units. The results shows that jig design have the most significant effect to the assembly time. Furthermore, the other factors: assembly design and workstation design are also show significant factors to assembly time. However, interaction combinations of two or three factors were not significant to assembly time. The most productive assembly line design which achieved the lowest assembly time is the combination of one operator, with rectangular jig and work station design sitting. Meanwhile the working posture of workstation design that provides the lowest RULA score was sitting position, it provided score 2 which is safe.

1. Introduction
An assembly line is designed by determining the sequences of operations to manufacture of components as well as the final product. Each movement of material is made as simple and short as possible, with no cross flow or backtracking. All operations performed along the line are balanced. Design of assembly line plays the important role in manufacturing which will directly influence its productivity.
Previous researchers [13], [19-20] explained assembly line is a widely used in production systems. The main objective of assembly lines designers is to increase the efficiency of the line by maximizing the ratio between throughput and costs. Chow [5] stated that “A simple process design criterion is to balance the assembly line so that each operation takes approximately the same amount of time. A balanced line often means better resource utilization and consequently lower production cost.” Jig is a special tool used for locating and firmly holding work piece in the proper position during the manufacturing or assembly operation. It also guides the tool or work piece during the operation. Jig is designed to increase the productivity of operation assisting worker to do job easier, faster and more comfortable.
Meanwhile, applying principles of ergonomics in the job environments such as improving working posture and workstation design as part of ergonomics efforts on enhance productivity and safe working condition have been extensively discussed by many authors [7] [8] [2]

[22]. The studies discussed ergonomics intervention may improve productivity, quality, operators’ working condition, occupational health and safety (OHS), and even cost effectiveness. The areas of working environment studied include workplace layouts, working tables and chairs of appropriate height, fixing hand-tools, better lighting and job rotation and also working postures.
This research studied several parameters afore mentioned:
i.e. design of workstation, design of assembly process, design of jig, their effects to productivity in the assembly line of plugs. Other variables such as equipment and skill of worker which may contribute to productivity are assumed kept constant. The hypothesis to be tested that either one or more of the parameters or combinations of parameters contribute to better production performance in this case assembly time or cycle time.
Two designs of jig were introduced, one has rectangular shape and the other has line or vertical shape or vertical orientation. Two design of assembly were tested one with single operator and the other with two operators.
Design of workstation was created by applying common industrial practices in assembly line i.e. standing or sitting position. For working poster assessment, RULA
(Rapid Upper Limb Assessment) analysis was conducted to examine different workstation designs effect to safe working postures.
2. Methods

widely used in the household, it was not a complex in design and components. The design of product is shown in Figure 1. This electric product is a plug product number BS 1363, it has 8 components. These are: base cover, neutral pin, earth pin, live pin, fuse holder, fuse, top cover and one screw. The dimension of the product is shown as Figure 1. Plug can assume as rectangular block
(dimension 51mm X 49 mm X 21 mm) with 3 pin (earth, neutral and live terminal pin). The central point of live and neutral pin is located 22 mm below the central point of earth pin. The distance between central point of live and neutral pin is also 22 mm. Accuracy of position and dimension of the plug’s pin are important when design the jig, this is to let plug able to locate and secure through the jig.

Figure 2 Two jig designs, a vertical shape and a rectangular shape
2.3 Design of Assembly line

Figure 1 Plug design and dimensions
2.2 Design of Jig
The purpose of jig on this research is holding the plug’s earth pin with cover in the proper position, other components locate and secure into the jig when the assembly process.
Two jigs were designed and produced by researchers, these designs were based on industry practice. The two were differentiated based on its orientation. The first one has orientation vertical shape in one line; the other has rectangular shape (see Figure 2). The size of the jig, the vertical one has 275 mm x 80 mm; the rectangular one has 136 mm x 145 mm. Both Jigs can accommodate 4 plugs at one time.

Two designs of assembly line were created these were based on manufacturing practices one with single operator and the other with two operators. The process of designing assembly as follow: at the first stage was to recognize components and the second stage was to comprehend assembly processes of product which is
BS1363. Once it has done, the assembly processes sequence were determined. These sequences as follow: put plug’s base cover on the jig, insert the child components (neutral pin, earth pin, live pin, fuse holder and fuse) into the base cover. Then, assembly the top and base cover together by screw. For screwing process, the jig is flipped and tightens with the screw driver powered by air pressure. The sequence planning for the assembly process of electric plug is presented in the precedence graph below:

1 – Place base cover on jig
2 – Insert earth pin
3 – Insert neutral pin
4 – Insert live pin

5 – Insert fuse holder
6 – Insert fuse
7 – Put top cover
8 – Screwing process

Figure 3: Precedence graph of plug assembly
Table 1is shown the result of each assembly task based on the precedence graph constructed in Figure 3. To obtain the balance of time for two operators, the assembly tasks assigned for each operator should be equal for eliminating the waiting time of another operator.

process
According to the table above, the total time for assemble one electrical plug is 19.00s. The single operator did all the tasks from the beginning to the end of assembly processes. For design of two operators, in order to obtain a good line balancing for 2 operators, the total assembly time must divide equally into two, which is 9.5 sec.
Hence, the most nearly cumulative assembly on Table 1 is on task 5 which is 9.66 sec. This means that the first operator will stop at the end of task 5 which is insert fuse holder. The second operator will start from task 6, insert fuse to final assembly. Assuming that there were work in process, therefore, the second operator did not required waiting for the first operator and could start the experiment at the same time.
2.4 Design of Workstation
Workstation design of an assembly line may contribute to performance of workers when he or she performed his/her job on position either standing or sitting. Grandjean [11] has made exploration on work surface height for different kinds of jobs. He proposed precision work for men should be set at 100-110 cm, light work around 90-95 cm and heavier work around 7590 cm. Since the assembly of plugs is considered as a light work, the workstation design for assembly was set at the height 91 cm for either standing or sitting position.
2.4.1 Standing Position
Figure 4 shows isometric, and front side views, while performing the task with an operator and in standing position. The table height is fixed to 91 cm.

2.6 Experimental Procedure
Two groups of worker participate in this experiment.
Each group has two subgroups, one with single operator and the other with two operators. These two groups will be compared and test whether their performance were the same, and whether the results of experiment were consistent. Each group performed 8 different sets of assembly process according to the full factorial design. Thirty two repetitions for each different set of assembly were done.
Each set was selected randomly, once it was selected, 32 plugs were produced. Hence, total of electric plug required to assemble for each group are 256 electric plugs. Measurement of performance for this experiment was the assembly time required to finish one product. Before recording the assembly time, the performance of each group was tested to ensure their work has reached a consistent performance. The assembly time or cycle time was recorded by using stop watch. This assembly time became the dependent variable, while different factors were set as independent variables.
2.7 Subjects
The subjects participated in this experiment were young workers age in average 24 years old, all were male subjects. Their height is on range of 170 – 180 cm. They have experiences and involved in industrial works for less than a year. Training to assembly this product was

The First test is to verify whether two groups of workers have different quality of work or performance.
This is necessary to make sure the inferences made from the results may work for both groups. Hence, the F test and t-test were used to examine whether two groups showed different performance. The F test were used to verify whether the group has significant different in variance. Based on the F test result, these two groups then were tested for t-test: paired two samples for means.

...rP os t 9-605-069 REV: MARCH 6, 2013 AMY C. EDMONDSON Phase Zero: Introducing New Services at IDEO (A) op yo In July 2002, Douglas Dayton looked out across the space where designers, engineers, human factors experts, and other specialists worked in teams and reflected that it was not easy to evaluate the recent project carried out for mattress manufacturer Simmons. Dayton was a design engineer and head of IDEO’s Boston office. IDEO was a design and innovation firm known for the extraordinary range of products it had designed and its innovative approach to the design process. For the Simmons project, IDEO had embarked on a service that was not intended to result in a tangible product, at least not right away. Whereas a typical design project progressed through four phases designed to “do the thing right,” this service, known as “Phase 0,” was intended to help a client “do the right thing.” Rather than design a new product based on pre-specified needs, Simmons had asked IDEO to help it “look for unmet needs that exist and to identify new product opportunities.” The project proposal, entitled “Understand and Innovate,” described Phase 0 services as helping clients understand the world in a new way and innovate accordingly. At first glance, mattresses were not exciting territory for the firm, but as the team researched mattress consumers— conducting literature reviews, site visits, and interviews with customers and salespersons—they grew intrigued...

Challenges of Mobility

...without being prepared to cope with the occurring resistances against the change. Consequently, the owners (e.g. shareholders) should be aware of the challenges and need to be committed to see benefits of the new system in a rather long-term view. Below we listed different categories of challenges. Firstly, it is common to see skepticism when practices change or new policies are implemented because we all like to cope with a known environment and it is always a challenge to change one’s mind and attitudes. Employees often feel uninformed about why things are changing and they often get the impression that no one is supporting them with the transformational process. Open-space offices as proposed in the workspace design section or the change to use trust-based working time (job design section) could be two specific practices leading to resistance and skepticism because those practices could be a dramatic change for some employees. Besides, the view that turnover always has negative consequences has been common sense over the last decades and many employees (also those in responsible positions) grew up with this view. Telling them now that the new approach is to stay connected with former employees through an alumni system constitutes a major change for those employees who need to overcome the way they were handling turnover during their entire career. Secondly, the implementation of the described HR system to create value in the sight of mobility could be a huge investment for the...

...What is desktop publishing and why is it important? According to www.dicitionary.com, desktop publishing is the design and production of publications by means of specialized software enabling a microcomputer to generate typeset-quality text and graphics (Collins, 2012). In other words it’s a means of producing quality publications with computer software. In my opinion, Abode InDesign is the best program to use when completing the process of desktop publishing. Adobe InDesign allows designers to successfully create publications with ease of mind. Abilities such as various layout options, changeable workspace options and ability to export files to .SWF and .EPUB format for digital publications makes Adobe InDesign my top pick for desktop publishing. Adobe InDesign was released in 1999 as the successor of the most valued program Page Maker. The new and improved features make publication designing more fun and easier for designers worldwide. When creating any publication the first thing to determine is the media and the layout for the publication. By knowing which size and what the publication is going to apply to, the design process can be determined. With InDesign, new features like liquid design allows users to form a publication and have the ability automatically adjust content when you create an alternate layout with a different size or orientation. This saves time on reformatting the entire publication with a few simple clicks of the mouse. Other settings like alternate layout...

Research Abstract

...worked to analyze how new media facilitates design communication using shared work environments. Previous studies on this topic laid a solid foundation for creative convergence network studies. However, prior research had no way of incorporating sketching as a communication into the collaborative process. Because of recent technologies, the department now has the ability to incorporate freehand sketching into the collaborative process. This adds a new facet to the process of collaborating. We also explored three different programs commonly used on collaborative team projects: Cintiq tablets, and either flash drives, Tidebreak’s TeamSpot, or TeamViewer. The goal of our research was to examine how technology changes the approach to team design and how technology will aid the creative decision-making process. We worked to compare how group decision-making processes change when in different environments and when different technologies are used. We analyzed use of shared workspace, freehand sketching, keystroke patterns and how well teams work with current technology and software. Thereby, tracking the group’s entire decision-making process. The benefit of our research was two-fold. We contributed to the existing research of team psychology and how collaborative work environments aid the design process. We were also the first research team to conduct how being able to sketch and communicate through sketches adds ease to the design process. Conducting this research also...

The research focused on designing as an essentially human activity via consideration of the epistemological and ontological issues involved in constructing coherent design theory. The research investigations led to a clearer understanding of the roles of ontology, epistemology and methodology in design research and this clarification enabled the construction of a post-positivist approach to engineering design theory that better includes social, environmental and ethical factors alongside the existing products of scientific engineering design research.

Promotion

...Besides the benefits from implementing the project, the cost in implementing is also important to be considered. The project would perform well only if we keep eyes on it during all procedures. The appropriate improvement would be proposed during the implementation of project in order to result in better achievement for the company. In conclusion, I would like to note that sales promotion is the element of the promotional mix that is aimed at increasing the volume of products sold via a trial or brand loyalty. The brand loyalty reflects the customer desire to buy the product or service of a given brand and depending on the level of brand loyalty that desire can be different. Sales promotion sends mixed signals with respect to building brand loyalty simply because it is hard to understand the amount of time or products needed to develop a buying habit that reflects brand loyalty. At the same time, sales promotion might be effective in building brand equity, or the existing value and association made by the consumer. Environmental friendly technologies can thus be said to have had a positive effect on motor sports and the world population at large since they have not only reduced pollution thus making the earth a safer place to live but they have also reduced the cost of living. This is in relation to soaring costs of fuel that have characterized the world markets in the recent past. (McKenna, 150-160) Top tier motor sports should therefore be encouraged to implement eco...

After doing some detailed investigations of the physical infrastructure of the orchards, orchard shacks, and the cold storage building revealed some ideas that we can implement in the network design. The investigation also showed that wireless technology would be the best solution between the three areas. With that being said the orchard area would be the only problem we would need to find out how big the orchard area is so we can install access points so a good signal can all ways be delivered. Determining the distance will also aid in the network design on what cables like fiber optics or RJ cables, as well as the selection of technologies and devices to meet the design goals. The number of buildings should be determined and what equipment they should contain which types of network devices needed for this landscape. 2.

Work in progress calculations: Units progress / day = 2000 units Through put time = 15 days WIP = 2000 *15=30000 Units No of workers = 42 WIP/worker = 30000/42=720 units Cellular operations Work in progress calculations Units progress / days = 2000 units Through put time = 1 days WIP = 2000*1= 2000 units No of works = 42 WIP/worker=2000/42=48 units Cycle time = throughput time /work in progress Traditional operations: 3*5*8*60/720=10 mins Cellular operations: 1*8*60/48=10 mins Hence we can infer that output per worker remains the same. 2. How does the performance of the traditional operation and cellular manufacturing system differ? (E.g. how Work in Process Inventory changes when cells are implemented? Throughput time (sewing & finishing): Traditional: 15 days / Cellular operation: 1 day No of sewing machines required: Traditional opert. 55 / Cellular operation: 84...
