This paper investigates the impact of provided service by the retailers and manufacturers on customers’ demand and members’ profit in a supply chain. It focuses on a supply chain structure with one manufacturer and a common retailer. The demand of customers depends on retailer price and service level. A game-theoretic framework is applied to obtain the equilibrium solutions for each entity in s...

The supply chain network design not only assists organizations production process (e.g.,plan, control and execute a product’s flow) but also ensure what is the growing need for companies in a longterm. This paper develops a three-echelon supply chain network problem including multiple plants, multiple distributors, and multiple retailers with amulti-mode demand satisfaction policy inside of pro...

Supply chain demand is often prone to fluctuations and instability. Known as the ‘bullwhip effect’, small variations in end-item demand create order and inventory oscillations that amplify from a downstream site to an upstream site. Applying a risk analysis approach, and assuming the bullwhip phenomenon as a constant reality, this paper will present the profits or losses that can accrue from va...

In literature, most papers examine several stochastic demand processes where order lead times are constant. In reality, manufacturing firms use inventory management software, especially MRP, which ignored lead time uncertainty. It is true that in certain special cases, lead time uncertainty has essentially no effect and can be ignored. Nevertheless more often, lead time fluctuations strongly de...

Demographic ageing is a process in Germany that set in decades ago and that affects many different areas within the economy, such as the social security system including health care. The ageing population is characterised by age-specific diseases and frequencies of illness. This suggests a structured planning of the complex health care market. A model that equally considers the supply and deman...

Collaborative planning, forecasting and replenishment (CPFR) coordinates the various supply chain management activities including production and purchase planning, demand forecasting and inventory replenishment between supply chain trading partners. This study proposes a systematic way of analyzing CPFR supporting factors using fuzzy cognitive map (FCM) approach. FCMs have proven particularly u...

In recent years the management of risk in supply chains has become an important issue in the scientific literature. This aspect is of primary interest in market side decisions of a company such as in the procurement of materials. So far, traditional supply chain planning methods solely focus on improving cost efficiency and reducing inventory buffers in supply chains. These approaches are succe...
