Capacity management for new ethical drugs is one of the most challenging tasks facing pharmaceutical manufacturers due to long lead times to acquire capacity, significant risks in product launching failure, volatile and growing demand and costs, and extremely high service level requirement....

In this paper, we consider the optimal investment and contribution adjustment problem for a multi-cohorts DB pension plan in an environment with parameter uncertainty. Preferences towards risk and ambiguity are modeled using the smooth ambiguity approach. Since the pension trustee is ambiguous...

This paper introduces a target benefit pension (TBP) model that incorporates longevity risk and stochastic interest rate. Previous models have not considered the dynamic nature of remaining lifetime, and this paper proposes an Ornstein-Uhlenbeck (OU) process to simulate average remaining...

This paper studies the optimal investment and benefit adjustment problem for a collective DC pension plan under longevity trend. We assume that the mortality hazard rate is a function of age and time, which extends the Makeham's Law and can describe the longevity trend. The contribution rate is...

This paper studies the optimal investment and benefit adjustment problem for a collective DC (CDC) pension plan in an environment with parameter uncertainty. We propose a smooth ambiguity framework to model the pension trustee's preferences towards risk and ambiguity. Since the pension trustee...

This paper considers an optimal investment and reinsurance problem involving a defaultable security for an insurer under the mean-variance criterion in a jump-diffusion risk model. The insurer is allowed to purchase proportional reinsurance or acquire new business and invest in a financial...

Defect engineering of metal compounds provides an effective strategy for customizing surface frustrated Lewis pairs (SFLP)and metal sites mediated CO2 coordination model.The indium-doped Bi4Ti3O12-CuIn5S8(CIS-IBTO)was synthesized by hydrothermal method. The Bi-Ti-In trimetallic sites mediated...
