In linear programming tasks, the optimal solution can remain same even with a significant deviation of initial data. Thus, when studying various problems in economic and mathematical analysis, question stability often arises. The problem finding schedule for processing perishable products is solved below. For example, we could refer to sugar beet, an important strategic product that degrades du...

We study an inventory control problem of a perishable product with fixed short shelf life in Dutch retail practice. The demand is non-stationary during the week but stationary over weeks, mixed LIFO and FIFO withdrawal. supermarket uses service level requirement. A difficulty that age-distribution products stock not always known. Hence, challenge to derive practical efficient order policies dea...

Purpose: The location of actors and production, transformation, commercialization distribution facilities generate the configuration perishable food supply chain (PFSC). logistics network design (LND) lead to different supply, storage environments result in flows, these operations have an impact on performance fresh agricultural products. Specifically, PFSC with seasonality, a temporary imbalan...

Three sequential models of consumption economies are considered, where consumers’ only endowment is money. The existence and unicity of temporary equilibria, the neutrality of money and the validity of quantity theory are investigated. In the ...rst two models ”money” is perishable; in the second one lending between consumers is possible. In the third model money is an asset and can be created ...

When one heats the yolk, changes occur in the fragile elements that serve to support the vital life force within the egg. The egg yolk, in many ways, is not very different from your own cells. Once your temperature goes above 105 degrees you will start to suffer serious health problems. Similarly, heating the yolk above 105 degrees will also start to cause structural changes in many of the high...

In this work, we investigate the value of information when the decision-maker knows whether a perishable product will be in high, moderate or low demand before placing his order. We derive optimality conditions for the probability of the baseline scenario under symmetric distributions and analyze the impact of the cost parameters on simulation experiments. Our results provide managers with deep...

Based on the characteristics of perishable goods, we extend the location-routing problem with distance constraints by adopting chance constrained goal programming approach to solve the uncertainty and to express the different priority levels of decisions. The random of depot construction costs and vehicle routing travel time is taken into account. Meanwhile, a two-stage genetic algorithm incorp...

Dr Silvia Estrada-Flores is Principal Consultant of Food Chain Intelligence, a consultancy business that provides advice in the practical aspects of the supply chain of perishable foods, from gate to plate; technical intelligence on the state of food logistics and food value chains; and operating procedures and plans to achieve an integrated supply chain. Silvia has worked extensively as a cons...
