Operations & Maintenance Business Model Transformation—Multiple Case Studies

Logical Operations in Theory-Building Case Studies

The logical operations involved in theory-building case studies include deduction (logical consistency and interconnection), induction (applying observations to theory), and abduction (creating, refining, and elaborating theory). The product of theory-building research is an account of a phenomenon in the form of words and other signs. Scientific quality control on theory is accomplished by com...

Modeling of Maintenance Operations

Operations and Maintenance 2

Large computer systems consist of many parts, only some of which contribute directly to the application for which the system was built. This collection of patterns describes several capabilities of a system that perform this background, supporting role. The roles of these patterns is to aid in application specific data, performance and health measurements, managing faults, and also managing the...

Model Predictive Control for Maintenance Operations Planning of Railway Infrastructures

This paper develops a new decision making method for optimal planning of railway maintenance operations using hybrid Model Predictive Control (MPC). A linear dynamic model is used to describe the evolution of the health condition of a segment of the railway track. The hybrid characteristics arise from the three possible control actions: performing no maintenance, performing corrective maintenan...

Teaching Business Demography Using Case Studies

Many faculty members consider using case studies but not all end up using them. We provide a brief review of what cases are intended to do and identify three ways in which they can be used. We then use an example to illustrate how we have used the case study method in teaching business demography. Among other benefits, we note that the case studies method not only encourages the acquisition of ...
