Purpose A product or service usually has multiple measurable characteristics, and its performance on different measures may vary and may change over time. Multi-criterion and multi-period performance benchmarking presents a challenge for management to determine performance gaps among comparable...

Purpose – Although software systems used to automate business processes have been becoming rather advanced, the existing practice of developing and modifying graphical process models in those software systems is still primitive: users have to manually add, change, or delete each node and arc...

Purpose – Process mapping is used to articulate the activities and procedures of business entities in a graphical way as pictorial images readily convey considerable information. The objective of this research is to provide evidence and a methodology to assist organizations in evaluating the...

The Latin hypercube design is a popular choice of experimental design when computer simulation is used to study a physical process. These designs guarantee uniform samples for the marginal distribution of each single input. A number of methods have been proposed for extending the uniform...

Supersaturated designs (SSDs) can save considerable cost in industrial experimentation when many potential factors are introduced in preliminary studies. Analyzing data in SSDs is challenging because the number of experiments is less than the number of candidate factors. In this paper, we...

Orthogonality has been considered as an important design priority in the design literature. This article provides a set of criteria to measure "how orthogonal" a design may be when it is not perfectly orthogonal. These criteria can be obviously applied to a wide variety of designs. Properties of...
