The challenge of automatically repairing bugs in programs to reduce debugging expenses and increase program quality is known as automated repair. To overcome this issue, test-suite-based repair techniques use a specified test suite an oracle alter the input faulty pass full suite. GenProg well-known example kind repair, which genetic programming used reorder statements already present program. ...

We consider an extension of the classical machine-repair model. As opposed to the classical model, we assume that the machines, apart from receiving service from the repairman, also supply service themselves to queues of products. The extended model can be viewed as a layered queueing network (LQN), where the first layer consists of two separate queues of products. Each of these queues is serve...

This paper presents the optimal flow control for a one-machine, two-product manufacturing system subject to random failures and repairs. The machine capacity process is assumed to be a finite state Markov chain. The problem is to choose the production rates so as to minimize the expected discounted cost of inventory/backlog over an infinite horizon. We first show that for constant demand rates ...

As composite materials are gaining wide acceptance in aircraft structures, the repair of damaged composites is becoming an important issue. Composite repair, however, has been performed more or less in a manual fashion, an integrated repair system is desirable. In this paper, an Internet-based advisory service (Repair Advisory Service, RAS) for composite repair is proposed to increase the effic...

We consider a production system containing a set of machines which are arranged according to a series-parallel configuration. The machines are unreliable and the failure rate of machine depends on the load assigned to the machine. The expected performance of the system is considered to be a non-monotonic function of its load. The issue of machine failure rate depending upon machine load brings ...
