Question 1: Fresh Burger is a locally owned fast-food chain that is currently considering the possibility of opening a new branch in Jubail. There are currently 3 options for the new site location: The first option is to rent a space in a popular area that is a walking distance away from both Sudair dis-trict and Al Nakheel beach. The annual rent for this option is 180,000 SR.
The second option is to rent a space in the male branch of Jubail University College (the College is open for 8 hours). Annual rent is 100,000 SR. The third option is in Fanateer Mall, which has plenty of parking. Although the restaurant would be located on the second floor, it is reasonably priced with an annual rent of 150,000 SR.
1. Develop a recommendation to the operation manager regarding which site their new branch should be located, include the following in your recommendation:
A. What is the main objective that the location decision should be based on? And Why?
B. Briefly discuss at least 3 factors that facilitated your decision of the preferred location? (Hint: Your analysis should be based on the knowledge you gained from Operation Man-agement course as well as your background information of the site options).
2. What process strategy is most appropriate for a restaurant? What are the characteristics of this process strategy in terms of volume and variety?
Note: your answer should be in your own words and the length should be around half a page: Spacing 1.5, Font 12).
Calculations:
Question 2: Nora is thinking about opening a cupcake shop and needs to buy a cake blender. Blender A has fixed costs of 100 SR and variable costs of 1 SR /unit. Blender B has fixed costs of 500 SR and variable costs of 0.5 SR /unit.
a) Using a graph, draw the total cost line for each option?
b) By looking at the graph, what is the volume at which the total cost of the two options are equal?
c) If Nora plans to sell 500units of cupcakes, which machine should she choose? What would be her profit if the selling price is 5 SR per cupcake?
Question 3: East Texas Seasonings is preparing to build one processing center to serve its four sources of seasonings. The four source locations are at coordinates shown below. Also, the volume from each source is provided.
