This paper describes the methodology used for development of a static capacity model. It is a well-known fact that no matter how sophisticated the dynamic models are, there is always a need for the simple spreadsheet model. The spreadsheet model helps one carry out simple and fast analyses whenever they are needed. At the Seagate Technology’s Recording Head Operations Wafer Manufacturing facili...

A game called the Quebec Wood Supply Game (QWSG) is a role-playing simulation based on the Beer Game for teaching supply chain dynamics, and, in particular, the bullwhip effect. In this context, this paper describes and compares two simulators based on the QWSG which may be used to study decision making and its impact on supply chain dynamics. We first focus on the direct implementation of the ...

This paper demonstrates a self-checking (self-validating) spreadsheet. This checking analyzes the meaning or semantics of using a parsing scheme. These semantics go beyond dimension, unit, and type checking to include the physical and mathematical formulae that dominate science, engineering, and mathematics. The spreadsheet is a client, JavaScript web application working with a server applicati...

Spreadsheet languages are very commonly used, by large user bases, yet they are error prone. However, many semantic issues and errors could be avoided by enforcing a stricter type discipline. As declaring and specifying type information would represent a prohibitive amount of work for users, we propose an abstract interpretation based static analysis for spreadsheet programs that infers type co...

Developments in Mobile Computing are putting pressure on the software industry to research new modes of interaction that do not rely on the traditional keyboard and mouse combination. Computer users suffering from Repetitive Strain Injury also seek an alternative to keyboard and mouse devices to reduce suffering in wrist and finger joints. Voice-control is an alternative approach to spreadsheet...
