In many areas of the economy, we deal with random processes, e.g., transport, agriculture, trade, construction, etc. Effective management of such processes often leads to optimization models with random parameters. Solving these problems is already v

In the work we consider a job shop problem with due dates under conditions of uncertainty. Uncertainty is considered for operation execution times and job completion dates. It is modeled by normal and Erlang random variables. We present algorithms wh

Classic approach based on deterministic models has been investigated for decades. After some time the research community realized that in real life problems there is a lot of uncertainty and if not captured, determined solutions are very often of lim

Many real problems are defined in an uncertain environment where different parameters such as processing times, setup times, release dates or due dates are not known at the time of determining the solution. As using deterministic approach very often

In the paper we consider an NP-hard problem of tasks scheduling with due dates and penalties for the delay in a flexible production cell. Each task should be assigned to one of the cell’s machines and the order of their execution on machines should

We consider strongly NP-hard problem of two-machine task scheduling with due dates and minimizing of the total weighted tardiness. Task execution times are random variables. We propose methods of intermediate review of solutions, the so-called ‘blo

Nowadays various types of data hiding techniques are used to conceal data in different types of digital content, e.g. image, video, audio, text, or even network traffic. Such methods can be utilized for nefarious purposes, for instance, for confident

While scheduling problems in deterministic models are quite well investigated, the same problems in an uncertain environment require very often further exploration and examination. In the paper we consider a single machine tabu search method with blo
