LOPTIS is an optimal decision support tool from Ketron Optimization
that is based on a mathematical programming production and distribution
model. It provides guidance for facilities location studies and for logistics
LOPTIS is data-driven so that it creates the model you
envision. You can model as many time-periods as appropriate and the periods can be of
different lengths. This feature supports analysis of inventory buildup and the
timing of investment in new facilities. The data-driven concept means that LOPTIS works
with the data supplied. For example, if you supply data for six plants, there
are six plants in the model; if you don't supply raw material data, there are no
raw material activities in the model; etc. Data are provided as tables.
LOPTIS has no built-in bias toward any industry or type of
enterprise. Think of it as a four echelon distribution modeling system with
some processing of the items being distributed. Viewed as a production and
distribution model, LOPTIS activities are:
RAW MATERIAL ACQUISITION & INVENTORY
The significant raw materials
are acquired at the various source locations and shipped to the plants.
FINISHED GOODS PRODUCTION & INVENTORY
Production of multiple
products takes place at the manufacturing sites.
Products are stored at
warehouses for delivery in later periods.
DIRECT SHIPMENTS TO MARKETS & WAREHOUSES
Products are shipped from
plants to markets and/or shipped to warehouses.
TRANSSHIPMENTS BETWEEN WAREHOUSES.
Products are shipped from warehouse to warehouse; this lets you model a hierarchy of distribution centers.
WAREHOUSE SHIPMENTS TO MARKETS.
These activities model shipping products from warehouses to markets.
The model data includes information on all of the candidate locations for new plants and warehouses plus the data to describe proposed expansion projects and divestitures. In effect,
LOPTIS tries all combinations of the expansion alternatives actions and selects the best combination. You can specify
how many new plants and warehouses you want included in the optimal solution.
