...As we know, business processes are critical to success of companies. This Business Process Management (BPM) simulation game gives us a better understanding of how the effective BPM impacts the whole business operation system. Also, this game demonstrates how we should do to improve the business process to make it more interconnected, intelligent and sustainable. From this game, we can see how BPM allows me to alter critical business process that affect not only the profit and customer satisfaction but also the environmental factors. In this game, firstly, we are given a HEAT map. The HEAT map is a component-based model of the company. It presents three types of management activity performed: Direct activities, Control activities and Execute activities. Also it shows us many groups of related business activities. It is a graphical representation of data where the concentrations of questionable factors are represented by corresponding colors in the model. This model provides us the useful information to analyze the current operation of AFTER, and helps us find out which area we should focus on to improve the process management. Then, we are required to create “As-Is” process maps. In order to pick a model that best fit the company, we have to know what’s the need of the company, what’s the problem the company is facing now and then decide how to solve these problems by improve the “As-Is” process. There are four tasks in the process, which are “collect caller information”...

When and why it becomes handy to use simulation. Steps used in simulation technique. Random selection in simulation. Advantages / benefits derived from use of simulation technique. Disadvantages /Challenges associated with simulation technique. Role of computer in simulation. Conclusion / comments. Definition of simulation: Simulation can be defined as a quantitative technique which describes a process by developing a model of that process and then conduct a series of organized trial and error experiments to predict the behavior of the process through time often with the aid of a computer. It is a method that is used to solve a problem in many areas of management, for example inventory management, queuing problems, profit analysis and project management among others. Model construction: A successful simulation model has to be carefully designed in order to achieve the intended predictive purpose. Therefore important factors have to be considered such as; i. It must be objective oriented. It must be constructed for a purpose and be able to achieve that purpose. ii. Critical variables and relationships. These must be identified and incorporated in model. However it is not essential or indeed desirable to include all variables in the model. iii. Simplicity...

...Crisis Management Simulations Preparing for the unexpected is what most businesses and governments strive to do. They hope to curb the next disaster in their favor. Or in worst-case scenario, businesses and governments hope to at least curb the crisis to be the least damaging to their image. The question people struggle with is how can these organizations prepare for every possible crisis they could encounter? It is simple: they cannot. However, with today’s technology many organizations have implemented crisis management simulations to better prepare for these worst-case scenarios as well as test the organizations’ tactics used in managing crises. Crisis simulations are relatively new and unheard of in some companies. Crisis management’s purpose is to engage “the whole organization in efforts to avert crises that may affect the firm, and to effectively manage those that do occur” (Pearson, n.d.). Organized crises are used in firms to simulate a crisis, such as a PR scandal or terrorist attack, and test the organization’s reaction to the event, how the crisis is handled, and if it is done effectively. These simulations are recently becoming popular to use in organizations because of new technology that gives them a real-time, fast-paced feel. Companies are now realizing that “as the development of new technology outpaces our ability to fully understand its impact, and as global reach relentlessly stretches organizational capabilities, ‘firefighting’ becomes a way of life” (Pearson...

...the probability distribution of the wait for repair services on JET’s copier. To model the probability of wait times in the JET Copies simulation, the JET partners generated a random number representing the probability of an occurrence of a breakdown. They then programmed a VLOOKUP function to match this breakdown probability to the corresponding “Repair Time in Days” column of the table. The result is the simulated time to get repair service for each breakdown occurrence. Interval between breakdowns The James, Ernie, and Terri purchased a copier just like the one used at their college office. When Ernie talked with someone in the dean’s office at State, he was told that the University’s copier broke down frequently often for 1 to 4 days. The partners became worried that their machine would also frequently break down. Although they could not get an exact probability distribution, James was able to determine that breakdowns occurred between 0 and 6 weeks apart. The probability of a breakdown increased as time passed. To model the time between breakdowns in their simulation, JET created a list of random numbers. Next, they applied the probability function f(x) = 2x/a2 0≤ x ≤ a. For this situation, the formula used is x = a √r. Since James estimated breakdowns occur zero to six weeks apart, the formula he used for this simulation is x = 6√r1. He then generated a list of random numbers and applied the formula to each random number. The result is the simulated time...

...Simulation 2 Write-Up During the simulation there were many different factors leading to varying results. One of the biggest causes for variation was in the performance of the worker. The worker had the impression that they were under a time constraint. The performance of the worker was usually kept constant until the last 5 or 10 drawings of cards, which is when the worker felt the pressure to draw cards faster. Another cause of variation was the shuffling of the worker. If the worker didn’t shuffle the cards thoroughly it would result in a varied outcome from normal results. This variation is considered a normal cause for variation because as the time constraint became more noticeable the workers would shuffle differently. This occurred more on the last few draws each round. One special cause occurred when the professor walked over to our workstation and had a conversation. This distracted the worker and simulated a special cause for variation. In order to improve the process, I would first designate a worker for shuffling the cards so we could eliminate time used passing the cards. This worker would then split the cards into two piles. Then I would assign two other workers the jobs of counting the cards after they have been separated. The workers would then both tell a single recorder the amounts to be recorded. This would be repeated with the designated shuffler. In order to assure that the second supplier is delivering the promised quality, we made a second...

...Monte Carlo Simulation Tutorial This tutorial shows how to use Microsoft Excel to develop Monte Carlo simulations without the use of add-ins or special software (such as @RISK or Crystal Ball). (Note, however, that there are some important advantages of using these dedicated software packages.) After completing the tutorial you should have a sufficient understanding of Monte Carlo concepts and Excel capabilities to begin building your own Monte Carlo simulations applied to a wide range of business problems, including the construction of short-term profit plans (otherwise referred to as “Cost-Volume-Profit” models, covered in Chapter 9 of the text). Monte Carlo refers to a widely used approach for solving complex problems using computer algorithms to simulate the variables in the model (e.g., a CVP model). Typically, an algorithm is developed to "model" the problem, and then the algorithm is run many times (from a few hundred up to millions) in order to develop a statistical data set for how the model behaves. Simple Example: Tossing a “Fair” Coin—Heads vs. Tails? For the simplest example, consider the basic coin toss. This is a process which has two possible outcomes (heads or tails), each with a 50% probability. In a million coin tosses, roughly half will be “heads” and half will be “tails.” A simple Monte Carlo simulation would support this conclusion. If you were to develop a spreadsheet with a random number generator resulting in 0 for “heads” and 1 for “tails,” then...
