Concept explainers
a)
To determine: Theoptimal sequence for the jobs.
Introduction: The Gantt chart is the kind of chart that is used to represent the amount of job done within a particular period. It is used to graphically represent the amount of job planned and done in a certain period.
b)
To draw: Gantt chart for the optimal sequence for the printing and binding jobs.

- The following set of seven jobs is to be processed through two work centers at George Heinrich’s printing company. The sequence is first printing, then binding.Processing time at each of the work centers is shown in thefollowing table: a) What is the optimal sequence for these jobs to bescheduled?b) Chart these jobs through the two work centers.c) What is the total length of time of this optimal solution?d) What is the idle time in the binding shop, given the optimal solution?e) How much would the binding machine’s idle time be cutby splitting Job Z in half?arrow_forwardUsing the FCFS rule for scheduling, the sequence is 1-2-3 For the schedule developed using the FCFS rule, the total length of time taken to complete the three suits (including delivery)= hours (enter your response as a whole number). Sunny Park Tailors has been asked to make three different types of wedding suits for separate customers.

- The mowry machine shop still has five jobs to be processed as of 8A.M today (day 29) at its bottleneck operation. The time since the order arrived, processing time, and promised due dates are given in the following table. The jobs are listed in order of arrival: Job Time Since Order Arrived (days ago) Processing Time (days) Due Date (days from now) A 12 4 10 B 7 3 24 C 5 10 16 D 3 8 7 E 1 4 13 Develope serpate schedules by using the FCF and EDS rules. Using FCF, the order is Using EDS, the order is The average flow time and average days past due are. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer.

From historical records, administrators can project the minimum number of nurses to have on hand during each day/time slot. This data is shown below. Shift Time Slot Minimum number of nurses needed 1 12 am-4 10 2 4 am-8 6 3 8 am-12 8 4 12 pm-4 12 5 4 pm-8 10 6 8 pm-12 14 Nurses must start work at the beginning of one of the four-hour shifts (starting as early as 12 am midnight or as late as 8pm evening) and work for eight hours. Nurses who begin working at 8 pm will work until 4 am the next morning. Formulate and solve the nurse-scheduling problem so as to minimize excess stagging while satisfying minimum staffing requrements. What is the value of total excess staffing?arrow_forward
