- able 4-4 on page 197 shows a relation called GRADE REPORT for a university. Your assignment is as follows: Draw a relational schema and diagram the functional dependencies in the relation. In what normal form is this relation? Decompose GRADE REPORT into a set of 3NF relations. Draw a relational schema for your 3NF relations and show the referential integrity constraints (as shown in Figure 4-5 on page 163). Draw an ER-diagram for your answer to part d above.arrow_forwardShow your step-by-step process using the SPECIAL PURPOSE LINEAR PROGRAMMING: ASSIGNMENT METHOD to solve this problem. Four Engineers are to work on 4 projects of Dora Company. The problem is to decide which engineer should be assigned to which project. Each engineer charges different fees on each project, due to distances of the projects and the complexity of the work. The cost of assigning particular engineers to particular projects are as stated below. The objective is to find the lease cost of assignment. Engineer 1 to Projects A, B, C, D = $11k, $8k, $10k, $7k respectively.Engineer 2 to Projects A, B, C, D = $6k, $5k, $3k, $8k respectively.Engineer 3 to Projects A, B, C, D = $4k, $8k, $10k, $9k respectively.Engineer 4 to Projects A, B, C, D = $11k, $10k, $5k, $7k respectively.arrow_forwardRBL’s directors are looking to expand into a new suite of services. Although they are doing quite well in their existing lines of business, analysts have identified some new areas for development. One of these is expansion into manufacturing prefabricated homes. However, this venture requires a large amount of funding. To raise additional funds to finance this new project, the company is considering issuing a new bond.Required: Prepare a short report which supports the case for issuing a corporate bond. In your report:a.Explain what a corporate bond is,b.Outline the characteristics of the bond market,c. Explain the benefits of issuing bonds to raise financing.arrow_forward
- 11-19 The Laurenster Corporation needs to set up an assembly line to produce a new product. The following table describes the relationships among the activities that need to be completed for this product to be manufactured. Modified Problem 11-19: Solve the problem, assuming the following data has changed for 3 activities: - Activity A: a = 4; m =7; b =6 - Activity B: a = 6; m = 9; b = 12 - Activity I: a = 4; m = 5; b = 7 Note to correct a textbook typo: Immediate Predecessors for Activity H are: E, F and G a) Develop the project network for this problem. b) Determine the expected duration, variance and standard deviation for each activity. c) Determine ES, EF, LS, LF and slack time for each activity. d) Determine the total project completion time and critical path(s). e) Determine the probability that the project will be completed in 34 days or less. f) Determine the probability that the project will take longer than 29 days or less.arrow_forwardAssign the 4 departments in Table X to locations A, B, C, and D, which are separated by the distances shown in Table y, in such a way that transportation cost is minimized. Use this heuristic: assign departments with the greatest interdepartmental workflow first. See attached table. a.Fill up the table attached. b. Compute the total transportation cost if the cost to move one workload 1 meter apart is P5.00.arrow_forwardAn electricity power plant was redesigned so that the old system consisting of a single large display screen which could be seen by all of a team of three operators was replaced by individual workstation screens for operators. This worked well until there was a problem which resulted in dangerous gases being released. The team of operators had great difficulty in finding the source of the problem and deciding what to do. Because they no longer have access to all the information, they have to spend time explicitly co-ordinating their understanding of the situation by talking to each other. Under the old system, the knowledge would be shared – one operator would know what was happening with another’s area of the plant without explicit communication. Although the team’s individual responsibilities would still have been clearly divided, the knowledge of the system would be shared. How could the new system of individual workstations be modified to make better use of distributed cognition?arrow_forward
- Assign the 4 departments in Table X to locations A, B, C, and D, which are separated by the distances shown in Table y, in such a way that transportation cost is minimized. Use this heuristic: assign departments with the greatest interdepartmental workflow first. (See attached table) Illustrate the configuration of the 4 departments in each of the 4 locations. Show the distances between departments and total interdepartmental workflows of department pairs.arrow_forwardplease solve all parts within 30 minutes.arrow_forward.

Project A has a net investment of $50,000 and net cash flows over a six-year period of $13,000 per year (NOTE: that project requires a reinvestment with the same cost and cash flow for another six years). Project B has a net investment of $48,500, but its net cash flows of $8,740 per year will occur over a 12-year period. If Quorex has a cost of capital of 14% for these projects, which project, if either, should be chosen, and what is its NPV?arrow_forward
