Correct predictions are in blue. If we detect only a subset of a labelled sentence, we highlight the caught part as blue, the missing part light blue. False positives are in green and false negatives are in red.

Problem Factory_Planning_I — Constraint detection

An engineering factory makes seven products -LRB- PROD 1 to PROD 7 -RRB- on the following machines : four grinders , two vertical drills , three horizontal drills , one borer and one planer . Each product yields a certain contribution to profit -LRB- defined as pounds/unit selling price minus cost of raw materials -RRB- . These quantities -LRB- in pounds/unit -RRB- together with the unit production times -LRB- hours -RRB- required on each process are given in a table . In the present month -LRB- January -RRB- and the five subsequent months , certain machines will be down for maintenance . These machines will be as follows : 1 Grinder -LRB- January -RRB- , 2 Horizontal drills -LRB- February -RRB- , 1 Borer -LRB- March -RRB- , 1 Vertical drill -LRB- April -RRB- , 1 Grinder and 1 Vertical drill -LRB- May -RRB- , 1 Planer and 1 Horizontal drill -LRB- June -RRB- . There are marketing limitations on each product in each month , given in a table . It is possible to store up to 100 of each product at a time at a cost of pounds 0.5 per unit per month . There are no stocks at present , but it is desired to have a stock of 50 of each type of product at the end of June . The factory works a six days a week with two shifts of 8 h each day . No sequencing problems need to be considered . When and what should the factory make in order to maximise the total profit ? Recommend any price increases and the value of acquiring any new machines . N.B. . It may be assumed that each month consists of only 24 working days .
