Hello,
I would like to get some advice on the following scenario and solution. Any better ideea are much appreciated.
Input Data:
00. 4 machines will be deliverd on sites, 2 big, 2 small. It is necessary to use 1 resource for each equipment - this machine 1, machine 2, machine 3, machine 4;
01. machines will be delivered on 4 sites, on different dates;
02. spacial constraint: maximum machines per site is 2;
03. the movement from one site to another is 3 days;
04. each machine has different productivity, big machine 100 sqm/h, small machine 80 sqm/h.
Required solution:
Optimize schedule in such a way that the activities are executed continously (or with minimum float) between them and find the order of movement of the equipment from one site to another.
My approach:
01. 4 milestones for resource production. Each milestone will produce 1 resource;
02. Created one resource skill with all 4 machines;
03. Activities have assigned 2 teams (maximum equipment per site), each team having the previous created skill;
04. The resource skill is of Quantity type, activities are of productivity type, resources in skill have productivities assigned.
05. Calculation and adjustment:
05.01 Step 1: scheduled with resource constraints to find activity durations and machine allocation for each activity;
05.02 Step 2: introduced activities for machine movement and linked them to the execution activities;
05.03 Step 3: introduced negative resource production at the end of each execution activity for machines that are used on the activity, and introduces positive resource production for machines that are used for the execution activity at the end of the movement activity. This way the the next activity will be delayed by the movement activity.
Is there any better solution?
Best regards,
Bogdan
