A decision support system for the university timetabling problem with instructor preferences
(Medwell Journals, 2006) Günalay, Y.; Sahin, T.
This study describes a decision support system for the university timetabling problem with instructor preferences, which uses Goal Programming (GP) as its modeling engine. The timetabling problem has been studied by many researchers and is an NP-complete problem. We model this difficult problem as a GP formulation and use its outputs in the decision support system. The GP model helps the user to consider the objectives of different parties involved in the problem. However, this increases the computational time of the model. Therefore, an iterative decision support system is proposed for generating the best scheduling alternative. Our model is tested using data from the Turkish Military Academy and its results are discussed.

Evaluation of the Turkish army soldier recruitment system and a model proposal for the optimization of soldier recruitment system
(2005) Yüksel, Ahmet
This study evaluates the Turkish Army recruitment system by measuring the total deviations of personnel inventories from the target value of inventory level. The target inventory level is the average of projected available human source in the next 19 years. In our study we offer a model that minimizes the deviations from the targeted inventory level of soldiers. The study also computes the zero value of total number of deviations for different service time durations in the military with applying different ages for the people of same birth year at the time of recruitment. The results of the study indicate that even without the flexibility of applying different ages, the model always achieves better results than the current recruitment system.

A goal programming approach to mixed-model assembly line balancing problem
(Elsevier, 1997) Gokcen, H.; Erel, E.
In this paper, a binary goal programming model for the mixed-model assembly line balancing (ALB) problem is developed. The model is based on the concepts developed by Patterson and Albracht [1] and the model of Deckro and Rangachari [2] developed for the single-model ALB problem. The proposed model provides a considerable amount of flexibility to the decision maker since several conflicting goals can be simultaneously considered.
