In recent years, the collaborative demand-to-supply management which strategically supplies products to the market so as to maximize profit is a critical role for establishing a sustainable company. However, sales sector and production sector, respectively, do not always work together for corporate-wide optimization. In the most case, sales sector is responsible for maximizing sales. On the oth...

The paper seeks to investigate the effect of the location of material and information decoupling points on the extent and role of demand planning in supply chains. In order to achieve this goal, the relationships between the location of two types of decoupling points are identified and necessary characteristics of demand planning process are recognized. The theoretical considerations are then e...

We solve a periodic supply vessel planning problem under demand and weather uncertainty, arising in offshore of oil gas production. Our study is motivated by the case Norwegian energy operator Equinor which supplied us with data. The aim to determine an optimal fleet composition least-cost schedule uncertain at installations conditions. present methodology incorporating metaheuristic within dis...

in this study, a new stochastic model is proposed to deal with a multi-product, multi-period, multi-stage, multi-site production and transportation supply chain planning problem under demand uncertainty. a two-stage stochastic linear programming approach is used to maximize the expected profit. decisions such as the production amount, the inventory level of finished and semi-finished product, t...

E nergy is one of the main and essential factors in economic growth. Electricity as one of the most important resources of energy supply for economic sectors on one hand, and as an index of welfare, on the other hand, is one of the economic development benchmarks. The growth of GDP will increase the demand for energy resources, including electricity. Hence, policymakers should pay at...

When addressing urban water problems, it is no longer adequate to consider issues of water supply, demand, disposal, and reuse independently. Innovative water management strategies and opportunities for water reuse can only be properly evaluated in the context of their interactions with the broader water system. An integrated linear deterministic optimization model is applied to Beirut, Lebanon...

Concerns related to climate change and security of energy supply is pushing various countries to make strategic energy planning decisions. In this regard, energy system modelling is an appropriate method to find out the utilization of current declining non-renewable energy resources and other possible scenarios. Consequently, it is available to consider various aspects of energy system decision...

This paper is focused on the tactical design of steel supply chain (SSC). A general mathematical model is proposed to integrate production and transportation planning in multi-commodity SSC. The main purpose is to prepare a countrywide production and distribution plan in an SSC with three layers consisting of iron ore mines as suppliers, steel companies as producers, and subsidiary steel compan...
