This research is a further development of our recent papers [2, 3]. A production system produces a given target amount by a given due date and has several possible speeds which are subject to random disturbances. The system's output can be measured only at present inspection (control) points....

We are concerned with a problem of scheduling a flexible manufacturing cell with random time operations. A job-shop production section comprises a set of n jobs (orders) and a set of m machines (processors). Each order consists of a chain of operations, each of which needs to be executed during...

The paper deals with the problem of production control with disturbances. The problem is applied to semi-automated production systems where the advancement of the process cannot be measured continuously but only in preset control (inspection) points. It is assumed that the production process can...

A two-level flexible manufacturing system is considered to be composed of several different production units Ui, 1≤i≤n, at the lower level and a section at the upper one. The section is required to produce a given target amount V by a given due date D subject to a chance constraint, i.e. the...
