Assignment $-9$

Part $1-$ Explain how modern vehicle routing and dispatching software and systems can support sustainability goals and objectives.

Part $2-$ Solve the below case study using the rules of sequencing $-$ FCFS$,$ SPT and and EDD approach. Please give your recommendations and show your calculations.

Luke's Balloon Shop

uke Steffie owns a balloon store and must fill balloons with helium and assemble them into certain configura$-$ tions today for six major parties. His six customer jobs all need to use the same helium tank $($that is$,$ the single$-$re$-$ source processor$).$ Each job consists of up to one$-$hundred

balloons. Luke is wondering the best way to sequence these jobs. Client $($job$)$ number five is his top customer. Luke's assistant store manager, Cindy Cheshire, wants to process them in sequential order $($i$.$e$.,1,2,3,4,5,$ and $6).$ Because the balloons lose air quickly, the company waits

until the day of the parties to fill them. The workload is hectic. Business is booming and growing about $15$ percent

Case Questions for Discussion: $1.$ Compute the average flow time, lateness, and tardiness for this group of jobs using Ms$.$ Cheshire's sequential order of $1($first$),2,3,4,5,$ and $6($last$).2.$ In what order would the jobs be processed using the SPT rule? Compute the average flow time, late$-$ ness, and tardiness for this group of jobs.

$3.$ Compare the answers in Questions $1$ and $2.$

$4.$ What are your short$-$term recommendations for this set of six jobs? Explain your reasoning.

$5.$ What are your long$-$term recommendations with respect to sequencing jobs at Luke's store? Explain your reasoning.
