Study Notes
Dynamic Model
- A dynamic model represents systems that change over time
- Certainty case in a dynamic model:
- All variables and parameters are known with absolute precision
- No ambiguity or variability in the system
- Predictable changes and no external shocks
- Deterministic relationships between variables
- Limitations of certainty in dynamic models:
- Overly simplifies real-world conditions
- Fails to account for uncertainties, variability, and dynamic nature of the external environment
Optimum Lot Size Model with Constant Demand (EPQ Model)
- Deals with constant demand scenarios and is a dynamic lot-sizing model
- Key components:
- Demand Rate (D)
- Production Rate (P)
- Setup (or Ordering) Cost (S)
- Holding (or Carrying) Cost (H)
- Shortage Cost (if applicable)
Risk Case in Dynamic Model
- Involves assessing and addressing uncertainties that may impact the model's behavior, outcomes, or predictions
- Characteristics of risk in production planning and control:
- Uncertainty
- Variability
- Complexity
- Interdependence
- Time sensitivity
P-System and Q-System
- Part of the Theory of Constraints (TOC), a management philosophy
- P-System:
- Focuses on maximizing productivity and efficiency of the production process
- Identifies and eliminates bottlenecks or constraints
- Emphasizes synchronizing the entire production process with the bottleneck
- Q-System:
- Manages and controls queues of work-in-progress (WIP) that accumulate in front of bottlenecks
- Manages the flow of work through the system
- Balances WIP levels to keep the bottleneck working continuously without overwhelming downstream processes
Material Requirement Planning (MRP)
- Basic calculations to determine components required from end item requirements
- Objectives:
- Inventory reduction
- Reduction in manufacturing and delivery lead times
- Realistic delivery commitments
- Increased efficiency
- MRP is a methodology used for planning and managing manufacturing operations
- Involves the use of software to assist with planning and scheduling of production processes
Just-In-Time (JIT)
- Inventory management method where goods are received from suppliers only as they are needed
- Reduces inventory holding costs and increases inventory turnover
- Importance of JIT:
- Reduces inventory waste
- Decreases warehouse holding costs
Enterprise Resource Planning (ERP)
- Complex information system that incorporates both internal and external information flows
- Need for ERP:
- Incorporates all business functions and external stakeholders
- Objectives of ERP:
- Drives the flow of information between all internal business functions
- Manages functions related to outside stakeholders
- ERP solutions:
- Address organizational needs, not selected islands of the organization
- Bring new culture, cohesion, and vigor to the organization
- Guarantee benefits even if the organization is a multi-plant, multi-location global operation
