The diagram in this topic illustrates a possible overlapping operation situation, assuming each operation requires a different resource group. Each resource group contains a single resource that is on-shift for the time represented in the example. …
67. Reformulate the following optimization problem as an equivalent LP problem. (xj are the decision variables and; aij and bij are the given coefficients) min 1 ∑ =1
The carpenter can afford to spend up to 40 hours per week working and takes six hours to make a table and three hours to make a chair. Customer demand requires that he makes at least three times as many chairs as tables.
In this section, we will show you an example of simulation. This is your first example so read it carefully. The Lajwaab Bakery Shop keeps stock of a popular brand of cake. Previous experience indicates the daily demand as given below: Using this sequence, simulate the …
A scheduling problem is NP-hard in the ordinary sense if partition (or a similar problem) can be reduced to this problem with a polynomial time algorithm and there is an algorithm with pseudo polynomial time complexity that solves the scheduling problem.
Answer: The key to solving queuing problems is to identify the mean arrival rate of customers and the mean service rate. In this case, on average, 15 customers arrive each hour.
The process in machine A consists of assembling 6 identical components, and the machine takes a random time following an exponential distribution of a mean of 30 minutes.
We will introduce three types of LP problems, demonstrate how to formulate them, and discuss some important issues. There are certainly many other types of LP problems.
Suppose that when task 1 is assigned to each of the two resources, in the new situation, it takes 6 minutes instead of 5 minutes. Also, suppose that when task 2 is assigned to each of the two resources, it takes 12 minutes instead of 10 minutes.
An average of 10 customers per hour come to a bank teller who serves each customer in 4 minutes on average. Assume exponentially distributed interarrival and service times.
