Consider the following maximum-claim reusable resource system with four processes (P0, P1, P2, P3) and three resource types (R0, R1, R2). The maximum claim matrix C is given as: R0 R1 R2 P0 4 1 4 P1 3 1 4 P2 5 6 13 P3 1 1 6 Where Cij denotes the maximum claim of the process i for resource j. The total number of units of each resource type is given by the vector: R0 R1 R2 5 8 15 The current allocation of resources is given by matrix A: R0 R1 R2 P0 0 1 4 P1 2 0 3 P2 1 4 1 P3 1 0 3 Answer the following question about the system: For the system state shown above, determine if a new request by process P2 for 6 units of resource R2 can be safely granted. (Remark: You can assume that the system state above does not yet accommodate this request.). Explain your reasoning. If the request cannot be safely granted, how should the system behave with respect to the request?
If a sporadic implicit deadline task set is schedulable under RM, will it be schedulable under RM after enlarging one of the deadlines (now it becomes an arbitrary deadline task set)? Note that we are still following the original RM priority order (not DM). What if we follow DM order?

In the model in Example 15.5, suppose bonuses and penalties are incurred for earliness or lateness. Specifically, suppose a bonus of $2000 is received if the project is completed within 60 days, an extra bonus of $1000 is received if the project is completed within 58 days, and a penalty of $1000 is incurred for every full day past a project completion of 64 days. (For example, if the project is completed in 66.7 days, the penalty is $2000—two full days late.) Modify the model appropriately, and then run the simulation to find the distribution of the net monetary outcome (negative if a penalty, positive if a bonus). What is the expected value of this net amount? What is the probability of a $3000 total bonus? What is the probability of a penalty of at least $4000?

Three alternatives are being considered for an engineering project. Their cash-flow estimates are shown in the accompanying table. A and B are mutually exclusive, and C is an optional add-on feature to alternative A. Investment funds are limited to $5,000,000. Another constraint on this project is the engineering personnel needed to design and implement the solution. No more than 10,000 person-hours of engineering time can be committed to the project. Set up a linear integer programming formulation of this resource allocation problem.
(a) What is the total utilization? (b) Construct a preemptive EDF schedule for this system in the interval (0,18).Label any missed deadlines. In this and the next part, assume that each job that missesits deadline is still executed in its entirety. (c) Construct a preemptive RM schedule for this system in the interval (0,18).Label any missed deadlines. (d) Suppose we want to reduce the execution time of the task with period 3 to makethe task set schedulable (i.e., all deadlines are guaranteed to meet) with the preemptiveEDF algorithm. What is the minimum amount of reduction necessary?

The purpose of this question is to explore the concepts of team's velocity and project size. Consider three teams operating with the following velocities, Team (a) – 400 points per iteration Team (b) – 500 points per iteration Team ( c) – 900 points per iteration Each team operates with the following cadence, Team (a) – 2 weeks per iteration Team (b) – 5 weeks per iteration Team ( c) – 3 weeks per iteration We also have the system test team that needs to integrate and test the complete application and cannot test a part of it. Consider three projects with the following sizes in points, 3000, 6000, 9000. Question is which team should engage with which project? The goal is for all three teams to complete their respective projects at the same time, and hence to enable the system test to start verification without waiting for anyone? Team (a) should receive a project with 6000 points Team (b) should receive a project with 3000 points Team (c) should receive a project…
Assume for convenience that demand is constant, the stock keeping unit (SKU) has been stored in k locations of identical size, and all picks are from a single active pick location until that location is exhausted. Then the inventory cycle may be imagined as consisting of k periods, each devoted to a particular pick location. The space utilization in period i is k-(i-1)-12/1 k-i+ k-(i-1) Thus, the average of the space utilization (ASU) of all k periods is asu= (1) The space utilization (SU) of the whole k periods is su = k = k i=1 2 k-i +1 i=1 k-i+ k-i +1 Σk-i+ i=1 k Σ(k-i+1) Use MATLAB® to write the functions to calculate "asu" and "su" of input "K". Employing these functions, program the script to draw the curves that show how both "asu" and "su" increase with additional storage locations, but at a diminishing rate.
