The data for a single-machine problem of sequencing production work for the seven customer arrived at time zeros are given below. Answer the following independent question. Which production sequence of given orders is obtained when we apply the displaying rule critical ratio (CR)? Illustrate your schedule on a Gantt chart, and determine the tardy jobs. total completion time, total lateness, total tardiness, maximum completion time (makespan), maximum latencies, maximum tardiness, and average flow time from your Gantt chart. What production sequence will maximize the total flow time of these orders? What is the total flow time of this sequence? Assume that $10 paid as penalty for each order completed after its data time. Which scheduling performance criterion and sequencing rule (approach) should be used in order to determine the optimal sequence of orders that minimizes the total penalty? Apply this scheduling rule, and calculate the cost of the resulting schedule? Assume that $5 is paid as penalty for each day of the latest completed order. Which scheduling performance criterion and sequencing rule (approach) should be used in order to determine the optimal sequence of orders that minimizes the total penalty? Apply this scheduling rule, and calculate the cost of the resulting schedule? To complete the cost of the resulting schedule? To complete the orders above in a shorter time, management wants to increase the number of machine. If management wants also the utilization of this work shop to be 100%, as not to waste money on investment, how many machines, which are identical to the existing machine, should be purchased to satisfy the management's purpose? which scheduling performance criterion should be taken into the account in this calculation? Which scheduling rule (approach) should be used to prove that the management's objective is satisfied? What is the value of the maximum completion time in this schedule? Consider the following project: Draw the project network illustration all precedence relations. Perform forward pass and backward pass to determine all earliest start, earliest finish, latest start and latest finish times. Identify the critical path. Ignore any crash program to the activities. What is the project duration? Assuming that it is possible to crash the project by shortening the duration of the activities at an additional cost which jobs should be expedited for more economical cost if we assume 50 can be saved for each day reduced from the project duration.
