The highly competitive airline market speeds up the needs in airline alliance or flight combination to cost down the operation as well as to enlarge the market share. However, the low reliability in some flight combinations may discourage the customer to buy such products. The low reliability of flight combination means that the connection of flights in some situation becomes impossible, and may cause...
The probability of union events is always important in management science. Many real life applications use such probability in their core implementations. The most popular method to calculate the probability of union events is the Inclusion-Exclusion Principle (IEP), which originates from the idea of Abraham de Moivre (1718). However, the computation complexity is exact O(2n), and no matter what the...
An integer programming problem is a mathematical optimization or feasibility program in which some or all of the variables are restricted to be integers. In many cases, the problems can be divided into integer linear programming (ILP) problems and integer non-linear programming (INLP) problems. A more complex problems are mixed integer programming (MIP) problems. There are many algorithms to well...
This paper proposes a novel approach to improve the performance of a business process without increasing cost. A business process usually consists of multiple tasks connected by their precedence relationships. These tasks are done by some persons who may be normal, sick, or absent. Therefore, the performance of a business process is stochastic in nature, and it can be modeled by the stochastic-flow...
Today, the pressure of economic globalization pushed many manufacturers to move to the developing countries and to start the lower-cost labor-intensive manufacturing (LIM). For example, China is called the world factory in the global economy. The performance evaluation for such kind of labor-intensive process is important for these developing countries. The traditional productivity-based performance...
Since network analysis has been a formal topic in Operations Research as well as in Reliability, researchers may need to validate their models or theories with large scale feasible graphs for test. This paper proposes an algorithm to generate a large scale undirected capacitated/uncapacitated graph for applications. Conventionally, NETGEN is employed for such purposes. But this program is about 30...
