The uncertainty set consists of a finite set of scenarios occurring with equal probability. This paper investigates a portfolio optimization problem under uncertainty on the stock returns, where the manager seeks to achieve an appropriate trade-off between the expected portfolio return and the risk of loss. Finally, a well-known logistics company in Taiwan is chosen to demonstrate the excellent performance and the aptness of the proposed ordering method. Sensitivity analysis is conducted to explore the impacts of changing the values of relevant parameters on the total supply chain cost, the total number of orders and the total number of opened members.

It is also shown that the performance of the proposed combined multi-period demand ordering method is superior to that of the lot-for-lot ordering method. The good performance of the proposed heuristic method is verified through a comparison with the optimal solution method. obtain a better initial feasible solution. Two important properties are introduced and used to. This study formulates a novel mixed-integer programming lot-sizing model for arborescent supply chains with discrete-period variable demand and then develops an efficient two-phase heuristic method, in which a combined multi-period demand ordering policy, rather than the lot-for-lot ordering policy usually assumed in previous papers, is adopted. Also, on-line courses will be available in due course.Ī. Please visit my website as there're interesting published articles in international magazines and journals that can be downloaded for use. Contributors are encouraged to use the Microsoft Excel spreadsheet programs in their works, troubleshooting and best practices. I'm opened to receiving topics with a brief summary that can be developed into book chapters for this highly important project, which could be in a two- volume series. I'm presently seeking exp ert process engineers with in-depth knowledge in the various fields of process engineering and to include new topics such as Sustainability, Health, Safety and Environment, Energy Efficiency and Conservation, Process Integration, Process Control, Reactor Design, Fine Chemicals, Water and Waste water treatment, Food Engineering, Biochemical Engineering, Alternative Sources of Energy (e.g, Solar, Wind, Tidal, Biomass, Hydroelectric, etc.), Process Safety and Process Safety Management, Carbon Capture Sequestration for the twenty first century and beyond.

The title is: Rules of Thumb for Process Engineers. I shall be editing a new book in the 4th quarter of 2019 to be published by Scrivener-Wiley in due course.
