摘要:線性規(guī)劃模型及其應用學者們常常用模糊集理論或概率論來處理這種不確定信息。為了尋求一種簡單而準確地刻畫方式,本文考慮用區(qū)間數(shù)描述這些系統(tǒng)的影響指標,建立基于區(qū)間數(shù)的線性規(guī)劃模型。針對運輸系統(tǒng)優(yōu)化決策問題,本文將系統(tǒng)運費、供給量、需求量和預算費用描述為區(qū)間數(shù),建立基于區(qū)間數(shù)的運輸優(yōu)化多目標線性規(guī)劃模型,給出算法步驟,通過實例分析來驗證該模型的可行性和準確性。
Abstract: Linear programming model and its application scholars often use fuzzy set theory or probability theory to deal with such uncertain information. In order to find a simple and accurate way of depicting, this paper considers the use of interval numbers to describe the impact indicators of these systems and establish a linear programming model based on interval numbers. For the transportation system optimization decision problem, this paper describes the system freight, supply amount, demand amount and budget expenses as interval numbers, establishes a multi-objective linear programming model based on interval number for transportation optimization, gives the algorithm steps, and verifies the feasibility and accuracy of model through case analysis.
