ADD Optitra – Inventory supply planning software.
The software is designed to create inventory supply schedules and to estimate the balance of warehouse stock within the set planning period and with specific consumption behavior (customer demand).
Supply planning can be manual, automatic or semi-automatic (custom). Automatic planning employs the so-called logistic stock management models based on warehouse stock balance control (constant or periodic) and its renewal at reorder levels.
The scope of supplies and intervals between them can be constant or variable depending on the selected model. Stock balance (warehouse stock and inventory on the way) at the beginning and the end of each month as well as minimum, maximum and average stock balance for the whole planning period is calculated on the basis of inventory supply schedule:
- Stock balance;
- Scope of supplies;
- Intervals between supplies.
These calculations may be used for inventory rationing. Several supply schedules can be made for every inventory item or for every storage area (central warehouse, company warehouse, workshop warehouse) or for every single supplier.
ADD Noza, software for inventory stock rationing.
The software is designed to calculate the baseline minimum of average annual warehouse stock level (inventory items and commodities) that guarantees required service rendering to the customers with the planned consumption behavior (customer demand) and the chosen strategy for stock renewal.
The calculation covers quantities, price and average daily consumption of available stock levels.
Stock level of each inventory is calculated as a sum of three components: level of current, reserve and prepared stock level. The levels are calculated on the basis of previous statistics and planned demand in inventory for the coming scheduling period.
When such statistics is unavailable the user can enter the information (including stock levels) he compiled using expert appraisals.
Several variants of stock levels can be created simultaneously for each inventory item or commodity or for storage area (central warehouse, company warehouse, workshop warehouse) separately.
ADD Plapo, software for traffic flow improvement.
Development of an efficient model of transportation support for a company is a complex task requiring:
- Complete restructuring of pricing and motivating transportation providers (based traditionally on machine hours and ton-kilometers and not result and quality oriented);
- Building prices system for recording, planning, management and control of transportation and logistics;
- Use of efficient logistics patterns (i.e. efficient distribution, traffic routes and allocation of infrastructure facilities).
While transformation in organization and efficient information support will be enough to solve the issues of the first two groups, making traffic flow more efficient will require application of specific mathematical algorithms that together with existing user interfaces serve as the basis for the traffic flow improvement software.
The software within a single shell (database) has the following features:
- Setting up and use of an electronic database for the transportation network structure and company facilities.
- Drawing efficient routes for any vehicle between objects and automatic creation of running schedules.
- Efficient distribution of vehicles and machinery over the objects in use.
- Arrangement of efficient relocation of process and maintenance teams between the objects in use based upon the type of work and costs.
- Efficient assignment of facilities to the maintenance teams (units, warehouses, etc.).
- Efficient allocation of facilities, warehouses and logistics bases.
ADD Plare, resource flow planning system.
This MS Excel-based resource flow planning software is designed for balanced modeling and simulation modeling of business processes in procurement, manufacturing, maintenance, accounting and others. Balance modeling is used for calculation of production output and consumption of various resources (inventory, power, machinery, manpower, funds, etc.) to define their quantity and costs.
Simulation modeling is a computer simulation of business process development in time that help to estimate:
- Runtime (start and completion) of every function and operation that constitute the modeled business process and precise duration of the process;
- Actual capacity of every function together with idle time and equipment work load and equipment idle time factors;
- The end and average levels of remainder (balance) of each resource in the modeled system.
Calculation of the balance based on the balance of availability, supply, manufacturing and release/consumption of resources can be carried out through two procedures of the System: “Calculation of Quantity” (material balance) and “Price Calculation” (value balance). Available tasks are:
- Estimation of requirements in materials, manufacturing capacities, manpower and funds under existing demand in finished products.
- Estimation of product output under existing manufacturing capacities, purchase quantity and warehouse stock of materials and supplies.
- Finding narrow spots (generated by shortage in resources) and ways to close them out.
- Estimation of semi-products and finished products costs under existing raw material and manpower prices.
- Estimation of profitability of business process under existing prices of consumed and produced resources.
- Estimation of transfer prices of goods and services of departments, affiliated branches or subsidiaries of the company (corporation) under specific levels of their profitability.
- Creation and analysis of different budget models (includes forecasting of financial accounting and estimation of financial ratios).
- Estimation of project resource intensity with a flexible tool for distribution of indirect (overhead) costs over projects, works and resources.
The model is designed for efficient distribution of the company hauling stock over established routes of people or inventory transportation when the number and capacity of vehicles are limited in order to minimize the transportation costs.
ADD Otsepo, software for evaluation of inventory and service suppliers.
The software is designed to rate the potential suppliers by multiple criteria:
- Complex evaluation of offers
- Two-level evaluation criteria system
- A number of variants of criteria weight allocation (weight of importance)

Scheduling Model.
Designed for even distribution of the scope of works over the planning timeframe in order to minimize the requirements in manpower, vehicles and machinery and/or total work cost.
Commodity distribution network improvement model.
Improvement of commodity distribution network (CDN) requires closing down of a number of warehouses (transfer points) and redistribution of inventory shipments from central warehouses (or from suppliers) to the customers in order to minimize CDN functioning costs taking into account capacity and throughput of warehouses and traffic routes.
Auction lot creation model.
The required volume of purchased goods and services is divided into lots placed for competitive bidding in order to minimize the number of lots at the defined competition level or to maximize the competition level with defined number of lots and in accordance with existing requirements and constraints.
Sensitivity analysis module for MS Excel (What-if Analysis).
The purpose of sensitivity analysis is to research the influence of input variables of the analyzed model (object) on output variables performance (calculation results).
Simulation modeling module for MS Excel (modeling of complex production systems).
Simulation model of a production system (business process) reproduces activity of modeled object in time simulating simple events (for instance, start or completion of engineering process) that change the condition of the object keeping logical interrelation and sequence of such events.
Generated simulation model can be replayed repeatedly (in step-by step and in automatic modes) making it possible to select different incoming parameter combinations and receive statistically reliable forecasts of modeled system activity and appraisal of its functions like efficiency, time for request processing, load and idle time of equipment, queue length, etc.
