supply chain

1. Suppose that you are going to upgrade a traditional fish supply chain. What would be your main challenges in such a supply chain? How would you handle them? 2. Extend the UP model for multiple products and multiple periods (i.e., formulate the multiproduct multi-period LIP). Consider a Supply Chain Network consisting of 2 potential distribution facilities, 4 customers, 2 products and 2 periods, and then, expand the model. Please do not to forget to present the model fully (including the indices/sets, parameters, and variables). 3. Consider that we have 4 available suppliers (A, B, C, and D) and we are going to prioritize them using AHP method. - Our criteria are (a) Cost, (b) Quality, (c) Reliability, (d) Eco-friendly Manner, (e) Delivery Time
