TOWARD BREAKING THE CURSE OF DIMENSIONALITY: AN FPTAS FOR STOCHASTIC DYNAMIC PROGRAMS WITH MULTIDIMENSIONAL ACTIONS AND SCALAR STATES
收藏 引用
SIAM JOURNAL ON OPTIMIZATION 2019年 第2期29卷 1131-1163页
作者: Halman, Nir Nannicini, Giacomo Hebrew Univ Jerusalem Jerusalem Sch Business Adm IL-91905 Mt Scopus Israel IBM Corp TJ Watson Res Ctr 1101 Kitchawan Rd Yorktown Hts NY 10598 USA
We propose a fully polynomial-time approximation scheme (FPTAS) for stochastic dynamic programs with multidimensional action, scalar state, convex costs, and linear state transition function. The action spaces are pol... 详细信息

Lot-sizing with non-stationary cumulative capacities
收藏 引用
OPERATIONS RESEARCH LETTERS 2007年 第4期35卷 549-557页
作者: Sargut, F. Zeynep Romeijn, H. Edwin Univ Florida Dept Ind & Syst Engn Gainesville FL 32611 USA
We study a new class of capacitated economic lot-sizing problems. We show that the problem is NP-hard in general and derive a fully polynomial-time approximation algorithm under mild conditions on the cost functions. ... 详细信息

Parallel-machine scheduling of deteriorating jobs with potential machine disruptions
收藏 引用
OMEGA-INTERNATIONAL JOURNAL OF MANAGEMENT SCIENCE 2017年 69卷 17-28页
作者: Yin, Yunqiang Wang, Yan Cheng, T. C. E. Liu, Wenqi Li, Jinhai Kunming Univ Sci & Technol Fac Sci Kunming Peoples R China Hong Kong Polytech Univ Dept Logist & Maritime Studies Kowloon Hong Kong Peoples R China
We consider parallel-machine scheduling of deteriorating jobs in a disruptive environment in which some of the machifies will become unavailable due to potential disruptions. This means that a disruption to some of th... 详细信息

Parallel-machine scheduling with deteriorating jobs and rejection
收藏 引用
THEORETICAL COMPUTER SCIENCE 2010年 第40-42期411卷 3642-3650页
作者: Li, Shisheng Yuan, Jinjiang Zhengzhou Univ Dept Math Zhengzhou 450001 Henan Peoples R China
We consider several parallel-machine scheduling problems in which the processing time of a job is a (simple) linear increasing function of its starting time and jobs can be rejected by paying penalties. The objective ... 详细信息

Single machine scheduling with release dates and rejection
收藏 引用
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2009年 第3期198卷 975-978页
作者: Zhang, Liqi Lu, Lingfa Yuan, Jinjiang Zhengzhou Univ Dept Math Zhengzhou 450052 Henan Peoples R China
In this paper, we consider the single machine scheduling problem with release dates and rejection. A job is either rejected. in which case a rejection penalty has to be paid, or accepted and processed on the machine. ... 详细信息

Complexity and approximability of scheduling resumable proportionally deteriorating jobs
收藏 引用
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2010年 第1期200卷 305-308页
作者: Gawiejnowicz, Stanislaw Kononov, Alexander Adam Mickiewicz Univ Fac Math & Comp Sci PL-61614 Poznan Poland Sobolev Inst Math Novosibirsk 630090 Russia
A set of independent, resumable and proportionally deteriorating jobs is to be executed on a single machine. The machine is not continuously available for processing but the number of non-availability periods, the sta... 详细信息

On the complexity of approximating a KKT point of quadratic programming
收藏 引用
MATHEMATICAL PROGRAMMING 1998年 第2期80卷 195-211页
作者: Ye, YY Univ Iowa Coll Business Adm Dept Management Sci Iowa City IA 52242 USA
We present a potential reduction algorithm to approximate a Karush-Kuhn-Tucker (KKT) point of general quadratic programming (QP). We show that the algorithm is a fully polynomial-time approximation scheme, and its run... 详细信息
