“…Bilir et al [25] addressed to the integrated multi-objective supply chain network and competitive facility location model to maximise profits and sales while minimizing the risks assuming that the demand can be determined by price and the utility function. Interested reader may refer to the surveys on transportation network design problems [26], multi-level facility location problems [27] and covering problems in facility location [28].…”

ÖzThis paper addresses to the facility location problem of ammunition stores considering the design of distribution network from stores to geographically dispersed army forces. The problem is to determine the construction sites of the ammunition stores among candidate sites and to give the decision on how many stores will be built from which kind. The problem also contains designing of a distribution network to concurrently determine the amounts of several military equipment transported from stores to army forces. A mathematical model is proposed to minimize the cost of the whole system, caused by the construction of the ammunition stores and the transportation of different equipment in diverse quantities from stores to dispersed army forces. The model is then improved progressively and several variants are presented to reflect the real-world conditions through a case study. Numerical results obtained from solving the case study using the proposed models coded in General Algebraic Modelling System (GAMS) are exhibited. The effect of the size of problem specific parameters on the model execution time is also investigated via experimental tests. The results demonstrate the promising problem-solving capacity of the proposed models, which can be applied practically. Bu çalışma, depolardan coğrafi olarak dağınık askeri birliklere dağıtım ağı tasarımını dikkate alarak mühimmat depolarının yer seçimi problemi konusunu ele almaktadır. Burada problem, aday bölgelerden hangilerine mühimmat depoları kurulacağını belirlemek ve hangi tip depolardan kaç adet inşa edileceğine karar vermektir. Ele alınan problem aynı zamanda mühimmat depolarından askeri birliklere sevk edilen pek çok askeri malzemenin miktarını belirlemek için bir dağıtım ağı tasarımı problemini içermektedir. Depo kurulumundan ve farklı askeri malzemelerin depolardan askeri birliklere farklı miktarlarda dağıtımından kaynaklanan toplam maliyeti minimize etmek için bir matematiksel model önerilmektedir. Bu model akabinde aşamalı olarak iyileştirilmekte ve gerçek hayat koşullarını bir uygulama vasıtasıyla daha iyi yansıtmak amacıyla modelin farklı versiyonları sunulmaktadır. Uygulamaya konu problem, önerilen modellerin GAMS (Genel Cebirsel Modelleme Sistemi)'te kodlanmasıyla çözülerek sayısal örnekler ortaya koyulmuştur. Probleme özgü parametrelerin büyüklüğünün model uygulama süresi üzerindeki etkisi de deneysel testlerle incelenmiştir. Sonuçlar, önerilen modellerin pratikte uygulanabilecek umut verici problem çözme kapasitesini göstermektedir. Pamukkale Univ Muh Bilim Derg, 26(1), 157-173, 2020 I. Kucukkoc, M. Acar 158 network design costs and operating costs are made. Contributing to this view, Berman et al. [15] proposed that modifying the underlying network can improve the accessibility to the facilities. Similarly, Peeters and Thomas [16]showed the significant impact of underlying network on optimal solutions to the p-median location-allocation problems.The UFLNDP assumes an infinite capacity for facilities, so that they can serve an infinite amount of demand...

“…However, researchers have usually addressed these problems by using heuristics and simulation tools. Astorquiza et al 36 review several multilevel facility location problems, underlining that only few works have used exact algorithms when the number of echelons and the complexity of the problem grow. Melo et al 7 arrive to similar conclusions, identifying that heuristic approaches represent almost half of the contributions reviewed.…”

Supply chain networks servicing upstream operations in oil and gas fields after the shale revolution

The recent irruption of shale resources in the oil and gas (O&G) industry has dramatically changed the paradigm for managing upstream operations. Unconventional production is largely driven by drilling new wells, yielding a much larger scale of material and service flows that need to be efficiently planned. This article presents an optimization framework for the design of integrated supply chain networks (SCNs) servicing upstream operations. Novel aspects addressed in this work are the integrated planning of material and service supplies; the economies of scale in operating, transportation and capital expenditures; the concept of waiting cost to quantify production losses; and the reverse flow of materials within closed‐loop supply chains. The merits of the proposed approach are assessed through real‐world case studies from the Argentine O&G industry. Optimal designs yield significant cost savings and confirm that the integrated planning of the SCN is critical for O&G operators after the shale revolution.

“…Prescriptions contain a certain number of unit-doses, equation 5is developed to balance the number of unit-doses received and the number of unit-doses dispatched in terms of prescriptions for each hospital. Equation (6) determines that for each hospital there must be at maximum the same number of prescription machines and storage machines. Satisfaction of demand in terms of unitdoses is modeled in (7).…”
