This paper investigates a supply chain consisting of single risk-neutral supplier and risk-averse retailer with the call option contract service requirement, where retailer’s objective is to maximize Conditional Value-at-Risk about profit. The optimal ordering quantity production are derived in presence requirement. Furthermore, by investigating effect level risk aversion on chain, it found tha...

We analyze the environmental benefits of operational flexibility that emerge in form less product waste during sourcing process by reducing overproduction. consider three different options for flexibility: (1) lead-time reduction, (2) quantity-flexibility contracts, and (3) multiple sourcing. use a multiplicative demand to model evolutionary dynamics uncertainty. then quantify impact key modeli...

We introduce MeSys, a meaning-based approach to solving English math word problems (MWPs) via understanding and reasoning in this paper. It first analyzes the text, transforms both body and question parts into their corresponding logic forms, and then performs inference on them. The associated context of each quantity is represented with proposed role-tags (e.g., nsubj, verb, etc.), which provi...

I describe two studies that were designed to illustrate the potential applicability of laboratory-derived ESP effects in trying to predict events of practical consequence in the “real world.” Both studies attempt to predict the behavior of sets of fi nancial indices over a designated week in the future. The studies followed up on earlier work on the prediction of scoring direction and scoring e...

T o avoid inventory risks, manufacturers often place rush orders with suppliers only after they receive firm orders from their customers (retailers). Rush orders are costly to both parties because the supplier incurs higher production costs. We consider a situation where the supplier’s production cost is reduced if the manufacturer can place some of its order in advance. In addition to the rush...

This paper presents a meaning-based statistical math word problem (MWP) solver with understanding, reasoning and explanation. It comprises a web user interface and pipelined modules for analysing the text, transforming both body and question parts into their logic forms, and then performing inference on them. The associated context of each quantity is represented with proposed role-tags (e.g., ...

Antitrust regulations are meant to promote fair competition in the market, but balancing administrative and legal costs with enforcement can be difficult when multilayered supply chains involved. The canonical example of this challenge is landmark Illinois Brick ruling, which limits antitrust damages only direct purchasers a product; for instance, consumers file claims against colluding retaile...

This article develops a model and analysis to provide insight into two effective remedies to increase supply chain resilience: (i) contracting with a secondary flexible backup supplier; and (ii) monitoring primary suppliers to obtain disruption risk information. To investigate the true value of these strategies, an analysis is performed under imperfect information concerning the disruption risk...
