Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Data-Driven Production-Service Planning: Ambiguity Aversion, Service-Dependency and Cross-Product Heteroskedasticity
数据驱动 生产-服务规划 歧义厌恶 服务依赖 跨产品异端性
2023/5/8
We consider a joint production-service planning problem with demand uncertainty, where the manufacturer aims to determine the portfolio of products with the associated service levels and the capacity ...
On the Production of Dissipation by Interaction of Forced Oscillating Waves in Fluid Dynamics
Equations of mixed hyperbolic and parabolic type oscillations BKW Calculus stability
2011/8/25
Abstract: In the context of some bidimensionnal Navier-Stokes model, we exhibit a family of exact oscillating solutions $\{u_{\epsilon}\}_{\epsilon}$ defined on some strip $[0,T]\times\R^2$ which does...
Voltage Collapse and ODE Approach to Power Flows: Analysis of a Feeder Line with Static Disorder in Consumption/Production
ODE Voltage Collapse Feeder Line Power Flows Static Disorder
2011/7/6
We consider a model of a distribution feeder connecting multiple loads to the sub-station. Voltage is controlled directly at the head of the line (sub-station), however, voltage anywhere further down ...
An Agent-Based Approach to Self-Organized Production
Agent-Based Approach Self-Organized Production
2010/12/28
The chapter describes the modeling of a material handling system with the production of individual units in a scheduled order. The units represent the agents in the model and are transported in the sy...

The production - inventory problem for ameliorating / deteriorating items with non-linear shortage cost under inflation and time discounting
Inflation Amelioration Deterioration
2010/9/20
In this paper, we discuss the production inventory model with time- varying production, time dependent demand and non-linear shortage cost under inflation and time discounting. Shortages are allowed a...
An EOQ model for deteriorating items with Weibull distribution deterioration, unit production cost with quadratic demand and shortages
Quadratic demand Weibull deterioration
2010/9/20
This article contains order level inventory models for deteriorating items with quadratic demand. The finite production rate is proportional to the demand rate and the deterioration is time proportion...
An improved upper bound on the Entropy Production for the Kac Master equation
Entropy Production Villani’s Conjecture
2010/12/8
In this paper we take an idea presented in recent paper by Carlen, Carvalho,Le Roux, Loss, and Villani ([3]) and push it one step forward to find an exact estimation on the entropy production. The new...
Optimization of a photobioreactor biomass production using natural light
Optimal control Biological systems Modeling
2010/12/3
We address the question of optimization of the biomass long term productivity
in the framework of microalgal biomass production in photobioreactors under the influence
of day/night cycles.
The limit of the statistic R/P in models of oil discovery and production
modeling oil production
2010/9/17
When assessing the oil reserves of a given region, often the statistic S = R/P is used, where R denotes the amount of proven reserves in the region and P is the current rate of production. This statis...

Optimal control of a production inventory system with Weibull distributed deterioration
Production planning continuous-review periodic-review
2010/9/15
This paper is concerned with the optimal control of a production inventory system with deteriorating items. It is assumed that the deterioration rate follows the two-parameter Weibull distribution. Th...
In shock wave theory there are two considerations in selecting the physically relevant shock waves. There is the admissibility criterion for the well-posedness of hyperbolic conservation laws. Another...
