To avoid common referencing mistakes, please note the following:
• In the reference list, place the title of the journal, not the specific journal article, in italics.
• In the reference list, give a full reference for a webpage not just the url.
• When referencing books in the reference list, the place of publication (e.g.
Dublin) precedes the name of the publisher (e.g. Gill and Macmillan).
• There is no need to bullet point or number your reference list.
• When citing websites within the main body of your assignment, use the (author, date) formulation rather than the url; i.e. write (Children’s Rights Alliance, no date available) rather than inserting the web address.
When quoting directly from an original source within the main body of your assignment, give the page number(s). Try to avoid excessive use of direct quotation.

For 2023 Green Fingers have developed the following forecast:
Demand No. of Jobs Probability
High 300 30%
Medium 200 40%
Low 120 30%
You are required:
a) Determine the fixed costs and break-even point for each capacity option. (6 marks)

option? (3 marks)

As the estimator for ABC Enterprises you have been asked to prepare an estimate for a potential service contract. The contract is for the service of diesel cylinder heads used in trains which the company has previously done on a sporadic basis.
The time required to service the first cylinder head is exactly 4 hours and similar work has been accomplished with an 85% learning curve. The customer wants you to quote the total time in batches of 12 and 20.
You are required:
a) Prepare a quotation based on a rate of €25.00/hour. (10 marks)
b) After preparing the quote, you find a job docket for this customer for five cylinder heads. From the information on the job docket, you conclude that the fifth cylinder
head took 2.5 hours to service. What do you conclude about the learning rate and
your quote? (10 marks)
A high-tech company makes medical devices using its highly skilled workforce. They can also access production facilities at a nearby sister company whose workforce is just as skilled.
They have a regular production capacity of 820 units which can be supplemented by a weekly overtime out of 40 units. The sister company can offer them extra capacity of 100 units monthly if required.
The forecasted demand and costs data for the next six months are as follow:
Month Demand
Costs and other data
1 770 Previous output level 760 units
2 790 Beginning inventory 0 units
3 810 Stockout cost €800 per unit
4 820 Inventory holding cost €400 per unit at month end
5 850 Unit Cost, regular time €1,500 per unit
6 860 Subcontracting €2,100 per unit
Unit Cost, overtime €1,800 per unit
Hiring workers €200 per unit
Firing workers €500 per unit
They are considering one of the following three aggregate plans:
• Plan A is to produce a level quantity utilising overtime, incurring back orders and
inventory charges. (7 marks)
• Plan B is to produce a base quantity of 800, using first, overtime, then subcontracting,
to meet demand. (7 marks)
• Plan C, a chase plan, using overtime and then subcontracting if regular capacity is
insufficient to cover monthly demand. (7 marks)
There is no need to start and end on the same output level and you have been asked to recommend one of the plans.
Prepare each of the plans, calculate the costs associated with each plan and make a recommendation explaining the reasons for your recommendation. (4 marks) (a) A particular operation uses a two-step sequence that all jobs in a certain category follow. For the group of jobs listed below;
Processing time (minutes)
Jobs a b c d e
Workstation A 27 18 70 26 15
Workstation B 45 33 30 24 10
(i) Find the sequence that will minimise the total completion time. (4 marks)
(ii) Construct a progress chart for the sequence of jobs. Clearly identify the amount of idle time at workstation B and the makespan of the batch of jobs. (5 marks)
(iii) What jobs are candidate for splitting? Why? If they were split, how much would idle time and makespan time be reduced? (Assume splitting the jobs in half) (5 marks)
(b) The table below contains information concerning four jobs that are awaiting processing at a work centre.
Job Processing Time (days) due date (days)
A 15 28
