We study a continuous-time version of the optimal risk-sharing problem with one-sided commitment. In the optimal contract, the agent’s consumption is a time-invariant, strictly increasing function of a single state variable: the maximal level of the agent’s income realized to date. We characterize this function in terms of the agent’s outside option value function and the discounted amount of t...

We address a multi-item capacitated lot-sizing problem with setup times that arises in real-world production planning contexts. Demand cannot be backlogged, but can be totally or partially lost. Safety stock is an objective to reach rather than an industrial constraint to respect. The problem is NP-hard. We propose mixed integer programming heuristics based on a planning horizon decomposition s...

This study deals with the problem of dependence between production and failure rates in the context of a multi-product manufacturing system. It provides an answer about how to produce (i.e. the production rates) and what to produce (i.e. which product) over a finite horizon of H periods of equal length. We consider a single randomly failing and repairable manufacturing system producing two prod...

Inventory control systems typically require the frequent updating of forecasts for many different products. In addition to point predictions, interval forecasts are needed to set appropriate levels of safety stock. The series considered in this paper are characterised by high volatility and skewness, which are both time-varying. These features motivate the consideration of forecasting methods t...

Inventory is lifeblood in an organization. Multiechelon inventory of Olympia paper mill, Khyber Pakhtonkhwa is optimized by efficient management of the organizational supply chain (SC). A supply chain is designed starting from raw material receiving from supplier up to finished good delivered to the customer. The on-going setup of the selected organization is traditional based on the experience...
