Introduction

This transportation model with 28 variables and a model with 10 pumps is written using sets and data. Then we print the result as a table. Hello, welcome back to Cerdas Inovasi Digital. In part two of this Lingo tutorial, we learn about sets and data. How to write a large model with just a few lines of formulas. Let's start. For large models, Lingo has sets and data. Sets contain groups of objects such as cities or months, along with their attributes. Data contains the numbers. The add sum function is for summing, and add for is for creating constraints for each member of the set. One line of formula can represent dozens of constraints. Problem four, airport expansion requires moving land from 4 surplus locations to 7 locations in need. The table contains transport distances in hundreds of meters. Total available land is equal to total demand, which is 1,331 cubic meters. The goal is to minimize distance multiplied by volume.

Result of Problem 4: total 17592 9

Problem five, the city of Lancaster needs 10,000 gallons per minute of water from 3 wells with 10 pumps. Each pump has a maximum rate and different operating costs, and each well also has a total limit. We find the rate for each pump with the lowest cost.

Result of Problem 5: minimum cost 772 0

Done. With sets and data, large models become neat and easy to modify. In part three, we create a 6-month aggregate production plan. Like, subscribe, and share. Goodbye.
