Scheduling a production shop. midwest parts supply (mps) is a fabricator of small steel parts that are sold as components to man

ufacturers of electronic appliances and medical equipment. in the mps fabrication department, steel sheets are subjected to a series of three main operations—cutting, trimming, and polishing—which must be completed in this order. each machine processes the jobs in the same order, so it is sufficient to specify a single job sequence in order to describe a schedule. no machine can process more than one job at a time.
this morning, ten jobs have been released to the shop by the erp system, and the production manager is interested in minimizing the time it takes to complete the entire schedule, usually referred to as the schedule makespan. the following table gives the number of hours required for each operation.
what sequence achieves the minimum makespan and what is the minimum length of a schedule?

The best scheduling to use to ensure that the ten jobs are done in the minimum amount of time is the SJFS.

<h3>What is Shortest Job First Scheduling? </h3>

This refers to the type of scheduling that makes use of an algorithm to process the shortest time to complete execution and reduces the average awaiting time for other processes to execute.

Please note that your question is incomplete so I gave you a general overview to help you get a better understanding of the concept.

kiruha [24]

Answer: 24.60 minutes (2dp)

Explanation:

The question is essentially asking that we find the Standard Time it takes to serve a customer.

To do this we would have to calculate the averages of the different elements and then use this to find the normal time which we can then use to find the Standard Time.

Element 1

= (3 + 4 + 4 + 3 + 3)/5

= 3.4

Element 2

= ( 9 + 8 + 10 + 11 + 10)/5

= 9.6

Element 3

= ( 7 + 8 + 6 + 7 + 8)/5

= 7.2

We then calculate the normal times by multiplying each of the individual means with their performance ratings.

That would be,

Element A

= 3.4 * 70%

= 2.38

Element B

= 9.6 * 110%

= 10.56

Element C

= 7.2 * 120%

= 8.64

We then add up the normal times to get the total normal time

= 2.38 + 10.56 + 8.64

= 21.58 minutes

Now we can solve for the standard time using this formula,

Standard time = Normal time (1+Allowance factor)

= 21.58 ( 1 + 0.14)

= 24.6012 minutes

= 24.60 minutes (2dp)

The time per unit customer served is 24.60 minutes.

If you need any clarification please do comment. Cheers.

Kamila [148]

Answer:

<em>Equivalent unit for conversion cost= 31,280 units</em>

Explanation:

<em>Under the weighted average method of valuation, to account for completed units, it is assumed that the entire degree of work required is done in the period under consideration. So there is no separation of the completed units into opening inventory and fully worked. </em>

<em>Equivalent units are notional whole units which represent incomplete work and are used to apportion cost between work progress and completed work</em>

Equivalent unit = Degree of completion × number of units

<em>Equivalent unit for conversion cost</em>

Item                                    units                                       Equivalent unit

transferred                       29,000        100%× 29,000    =          29,000

Closing inventory                3,000          76%×  3,000   =           <u> 2280 </u>

Total equivalent unit                                                                    <u>31,280</u>

<em>Equivalent unit for conversion cost= 31,280 units</em>
