统计代写|运筹学作业代写operational research代考|SAS for Operational Research

SAS (statistical analysis system) has very comprehensive products for all aspects of operational research, including data analysis, optimization, and matrix algebra among many others, so it is beyond the scope of this book to discuss every aspect of SAS. We will just examine a small part that will be most useful to operational researchers. Most operational research tools for modeling, analysis, and problem solving are found in SAS/OR (an operational research software developed by SAS), but some optimization features are also present in SAS/STAT (statistical analysis software), SAS/IML (interactive matrix programming with integration to R), SAS Enterprise Miner, and SAS/ETS (econometric and time series analysis software). A range of other products can be found at www.sas.com.

These days, there is plenty of software that can be used for operational research. The major reason why we selected SAS is because it has various optimization tools that can be used in a wide range of problems in operational research. Besides, SAS has strong data management capabilities that can handle very large datasets efficiently, and it can work with multiple datasets simultaneously. SAS has also a wide variety of statistical procedures and data-mining techniques.

Here is a list of some related SAS tools, but full range of SAS products can be obtained from $\mathrm{SAS}^{\oplus}$ :

• Base SAS: Data management and basic procedures
• SAS/STAT: Statistical analysis
• SAS/OR : Operational research
• SAS/ETS: Econometrics and time series analysis
• SAS/IMLi Interactive matrix language
• SAS/IRP: Inventory optimization
• SAS/SQL: Structural query language
• SAS/Enterprise Miner: Data mining with SAS

统计代写|运筹学作业代写operational research代考|Example of Using PROC OPTMODEL

The PROC OPTMODEL procedure includes the powerful modeling language and state-of-the-art solvers for various classes of optimization problems.

PROC OPTMODEL modeling language offers a modeling environment for building, solving, and maintaining mathematical programming models. PROC OPTMODEL provides an efficient environment for converting the

symbolic formulation of an optimization model into SAS. PROC OPTMODEL also simplifies data transformation to populate optimization models with data from SAS datasets.

PROC OPTMODEL can be used to build and solve optimization models, as well as to provide an environment for modeling tools. The results of optimization models built with PROC OPTMODEL can be saved in SAS datasets that may be submitted to other SAS product, including SASBASE and other optimization procedures in $\mathrm{SAS} / \mathrm{OR}^{\otimes}$.

统计代写|运筹学作业代写operational research代考|An Introductory Example

As an introductory example, consider the following transportation programming:
Suppose there are four warehouses in different cities. They have 1000,1500 , 2000 , and 2000 tons of paper accordingly. There are eight publishers in different locations. They ordered 200, 500, 700, 800, 900, 900,1000 , and 1500 tons of paper to publish some new books. The cost of delivering 1 ton of paper from each warehouse to publisher is listed in Table 1.2.

Assume that the data are saved in two SAS files as follows (see program “sasor_1_1.sas”): This code shows how the PROC OPTMODEL can be used to find the minimum cost for the transportation problem. This procedure takes the model as defined in the two SAS datasets-_d_trans” and “d_demand”-and finds the minimum cost flow (see program “sasor_1_2.sas”).
