Introduction

• TACTIC - created by Waterloo Manufacturing
  Software
• Advanced Planning and Scheduling software (APS)
• An aid to help manage the shop floor through
  planning and scheduling

3
Basic Scheduling

• Production Scheduling Software
• Generate detailed dispatch lists for individual
  production machines, units of labor and other
  manufacturing resources. 
• Setup and maintenance times for each machine and
  resource considered
• Considers the finite, or limited, capacity
  constraints of the machines being scheduled.
• Handles raw material limits and constraints
• Assists in scheduling jobs, worker schedules, and
  predicting time of completion of jobs

4
Advanced Scheduling

• Advanced Planning and Scheduling Software
• Considers shop floor capacity constraints
• Inventory and bill of materials constraints
• Inventory stocking and replenishing levels
• Predicts likelihood of on-time execution of
  forecast
• Shows which plant to run production
• Assists in lead time prediction
• Uses computer to calculate elapsed time of parts
  through routing

5
TACTIC Interface

• Windows style graphical user interface makes
  interaction intuitive and simple
• Visual analysis feedback using Gantt charts,
  tables, and comparison graphs

Visual Analysis Feedback Screen
6
Interface (contd.)

• TACTIC configuration
• provides a central database of inventory,
  capabilities, requirements, schedule, and status
  data
• Floor workers and managers can access TACTIC
  database info at any time from any terminal to
  keep up with schedule changes

7
Data Handling

• Capability Data
• Includes machine, tool, labor, vendor, and
  material availability
• Requirement Data
• Includes orders and their associated routing
  operations, bill-of-material, and item master
  relationships
• Able to interact with TACTIC to make changes in
  entered data

8
Data Handling (contd.)

• Wide variety of data transfer capabilities
• Data extraction from
• SQL ODBC databases
• Spreadsheets
• Binary Flat files
• ASCII

9
Features

• What if-tool
• Combines formal data and intuition to create
  detailed schedules
• Visualize problems
• Gantt charts, tables, graphs
• Interactively investigate any variety of data
  scenarios
• Error Handling
• Calculates violations and their causes
• Suggests possible solutions

10
Features (contd.)

• Data Analysis
• Detects bottleneck constraint
• What-if capability can show bottlenecks reaction
  to changes in data and scheduling
• Shows at which levels orders consume bottleneck
  resources
• Shows cost relationships with orders and
  materials/resources used

Possible Benefits

• Helps reduce cost of goods sold
• Reduces direct material costs, labor cost,
  overhead cost
• Reduces Inventory
• Improves scheduling leads to lower inventory
  levels and carrying costs
• Reduces Operating Expenses
• Reduces finished goods inventory, expediting
  costs, back-order cost, capital expenditure
• Increases sales
• Improves customer service, reduces lead times,
  increases quality
