Chapter 1: Methodology
Describe the phases associated with an Operational Research project.
Phase 1: Problem identification
• Diagnosis of the problem from its symptoms if not obvious
• Delineation of the subproblem to be studied
• Establishment of objectives, limitations and requirements
Phase 2: Formulation as a mathematical model
• Choice as to the appropriate model may be crucial to success
• ‘Data barrier’ and data-rich/data-poor environments
Phase 3: Model validation (or algorithm validation)
• Model validation, running the algorithm for the model on the computer in
order to ensure:
• the input data/computer program is free from errors
• the computer program correctly represents the model
• the results from the algorithm seem reasonable
Phase 4: Solution of the model
• Use of a standard computer package, or specially developed algorithm
• Different numeric scenarios to establish sensitivity
• Speed of processing (turn-around time) and the interactive/user-friendly
nature of many pc software packages.
Phase 5: Implementation
• Implementation of the results of the study; or
• implementation of the algorithm for solving the model as an operational tool
Discuss how you might ensure that an Operational Research
project is successfully implemented.
Implementation:
• necessary to ensure, when formulating the problem, that all the relevant technological and cultural constraints are known and, where appropriate, included in the model.
• continuous contact with the organisation, and specifically the client in the organisation (the person/people who have the problem)
o regular and positive communication with the client
o the result may surprise the client (i.e., it may not fit with their previously conceived ideas of what the solution would be), but the work that is being done should not
• giving the solution, and justification for the solution, in plain language, using terms the client will understand.
• ensuring that the action recommended in the solution is within the power of the client
