A variant of the hybrid flow shop (HFS) problem considering missing operations, transportation times and sequence-dependent setup times is investigated. Heuristic algorithms along with dispatching rulesand dispatching rules are used to solve the given problem. The objective function is minimization makespan. The computational experimets are conducted to test the performance of the heuristic algoirthms and dispatching rules. In order to depict the effect of the factors: number of jobs, number of machines, number of production stages, level of missing operations on the result, the additiol experimentes are carried out. The result of NEH heuristic with SPTF rule outperformed other heuristics for the proposed HFS problems.

Supply chain management is the managing of all processes of goods, services, and information from suppliers to customers. Transportation network design is an important part of effective supply chain management. This chapter presents the two-stage fixed-charge transportation problem in a supply chain to minimize the total cost containing the opening cost of distribution centers, transportation cost from manufacture to distribution centers and from distribution centers to customers, and fixed cost for transportation from distribution centers to customers. There are the capacity constraints on distribution centers in order to consider real life situations in this chapter. A constructive based algorithm and a population-based algorithm are proposed to solve this complex optimization problem. Taguchi experimental design is applied for determining the best combinations of parameters. The experimental studies are conducted to compare the performance of the proposed algorithms according to solution quality.

Personel seçim problemi işletmeler için oldukça önemli ve içerisinde birden fazla değerlendirme kriterini barındıran ve belirsizliğin olduğu çok kriterli karar verme problemidir. Çalışmada, Bulanık TOPSİS, Bulanık Gri ilişkisel analiz, Bulanık Waspas, Bulanık Aras yöntemleri kullanılarak çözüm amaçlı bir yaklaşım önerilmiştir. Personel seçiminde kullanılacak kriterlerin ağırlıkları bulanık SWARA yöntemiyle belirlenirken grup hiyerarşisi de değerlendirilmiştir. Önerilen yaklaşımın uygulanabilirliğini ve sonuçlarını göstermek için, üretim sektöründe faaliyet gösteren bir işletmenin depo sorumlusu seçme sürecine önerilen yaklaşım uygulanmıştır.
