[ 1 ] - Systems Risk Analysis UsingHierarchical Modeling
A fresh look at the system analysis helped us in finding a new way of calculating the risks associated with the system. The author found that, due to the shortcomings of RPN, more researches needed to be done in this area to use RPNs as a new source of information for system risk analysis. It is the purpose of this article to investigate the fundamental concepts of failure modes and effects ana...
[ 2 ] - Joint Optimization of Star P-hub Median Problem and Seat Inventory Control Decisions Considering a Hybrid Routing Transportation System
In this paper, we study the problem of integrated capacitated hub location problem and seat inventory control considering concept and techniques of revenue management. We consider an airline company maximizes its revenue by utilizing the best network topology and providing proper booking limits for all itineraries and fare classes. The transportation system arises in the form of a star/star net...
[ 3 ] - The Bullwhip Effect on the VMI-Supply Chain Management viaSystem Dynamics Approach: The Supply Chain with Two Suppliers and One Retail Channel
This work investigates the effect of different inventory policies of a supply chain model using the system dynamics approach which belongs to the class of Vendor Managed Inventory (VMI), automatic pipeline, inventory and order based production control systems (VMI-APIOBPCS). This work helps management to investigate the effect of different policies such as adding the VMI system or third party l...
[ 4 ] - Multiple Criteria Decision Making Combined with VRP: A Categorized Bibliographic Study
In this research author reviews references related to the topic of multi criterion (goal programming, multiple objective linear and nonlinear programming, bi-criterion programming, Multi Attribute Decision Making, Compromise Programming, Surrogate Worth Trade-off Method) and various versions of vehicle routing problem (VRP), Multi depot VRP (MDVRP), VRP with time windows (VRPWTW), Stochastic VR...
[ 5 ] - A System Dynamics Model for Joint Upstream and Downstream Partner Selection in a Supply Chain Consisting of Suppliers and Retailers
Firms no longer compete as autonomous entities and prefer to join in a supply chain alliance to take advantage of highly competitive business situation. Supply chain coordination has a great impact on strategic partnering and success of a firm in competitive business environment. In this paper, we propose a system dynamics simulation model for strategic partner selection in supply chain. Our mo...
[ 6 ] - Safety Risks Impacts Analysis on Construction Project Objectives Using a Hybrid Model of Fuzzy Expert System and Latin Hyper Cube Sampling
Background and aims: The construction industry has a high rate of fatal or nonfatal injuries and all around the world which remains one of the most dangerous occupations till now. Since project safety and measuring danger in the construction industry is a crucial subject, so this study aimed to measure the impacts of safety risks on the time and cost objectives of project using a hybrid method ...
[ 7 ] - The Integrated Supply Chain of After-sales Services Model: A Multi-objective Scatter Search Optimization Approach
Abstract: In recent decades, high profits of extended warranty have caused that third-party firms consider it as a lucrative after-sales service. However, customers division in terms of risk aversion and effect of offering extended warranty on manufacturers’ basic warranty should be investigated through adjusting such services. Since risk-averse customers welcome extended warranty, while the cu...
[ 8 ] - A Hybrid Dynamic Programming for Inventory Routing Problem in Collaborative Reverse Supply Chains
Inventory routing problems arise as simultaneous decisions in inventory and routing optimization. In the present study, vendor managed inventory is proposed as a collaborative model for reverse supply chains and the optimization problem is modeled in terms of an inventory routing problem. The studied reverse supply chains include several return generators and recovery centers and one collection...
[ 9 ] - A Novel Continuous KNN Prediction Algorithm to Improve Manufacturing Policies in a VMI Supply Chain
This paper examines and compares various manufacturing policies which manufacturer may adopt so as to improve the performance of a vendor managed inventory (VMI) partnership. The goal is to maximize the combined cumulative profit of supply chain while minimizing relevant inventory management costs. The supply chain is a two-level system with a single manufacturer and single retailer at each lev...
