  • Instructor Professor S. A. Irani
  • Team Members
  • Shaun Garrett (garrett.146_at_osu.edu)
  • Yolanda Langford (langford.16_at_osu.edu)
  • John Seeley (seeley.17_at_osu.edu)

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

11
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
