Concept explainers
Roy Creasey Enterprises, a machine shop, is planning to move to a new, larger location. The new building will be 60 feet long by 40 feet wide. Creasey envisions the building as having six distinct production areas, roughly equal in size. He feels strongly about safety and intends to have marked pathways throughout the building to facilitate the movement of people and materials. See the following building schematic.
Building Schematic (with work areas 1–6)
His foreman has completed a month-long study of the number of loads of material that have moved from one process to another in the current building. This information is contained in the following flow matrix.
Flow Matrix Between Production Processes
Finally, Creasey has developed the following matrix to indicate distances between the work areas shown in the building schematic.
What is the appropriate layout of the new building?

- 15.12 Tigers Sports Club has to select four separate co-ed doubles teams to participate in an inter-club table tennis tourna- ment. The pre-selection results in the selection of a group of four men Raul, Jack, Gray, and Ajay-and four women-Barbara, Dona, Stella, and Jackie. Now, the task ahead lies in pairing these men and women in the best fashion. The table below shows a matrix that has been designed for this purpose, indicating how each of the men complements the game of each of the women. A higher score indicates a higher degree of compatibility in the games of the two individuals concerned. Find the best pairs.

Tesla is launching a new model of their cars. It is known as the Tesla-model X. Their production facility in Chicago cannot fit the assembly line needed for making the new model. They bought robots, tools, and materials to expand the manufacturing facility. This assembly line is only going to make model-X's and no other models. Their layout is: a) Services Layout b) Product Layout c) Fixed Position Layout d) Process Layout 2. A country is only as strong as its citizens. Due to Bangladesh being a third world country, the crisis is everywhere. With a massive number of people believing in hard work for a minimum wage, these blue-collar employees are having the harshest time surviving this countrywide condition. They simply don't have the means to withstand this situation and that is where the government comes in to aid these people with essentials such as food and equipment (Tran) which will help them to stay afloat from this pandemic.

Clearly state the decision rule you use and complete the below table using the selected rule. Decision Rule Logic Longest work element Picking the candidate with the longest time to complete is an effort to fit in the most difficult elements first, leaving the ones with short times to “fill out” the station. Shortest work element This rule is the opposite of the longest work element rule because it gives preference in workstation assignments to those work elements that are quicker.
