Summary
This review covers three papers on inventory systems. It looks at different methods for optimizing inventory costs. Students learn about various techniques and their applications in different demand patterns.
Inventory's importance
Inventory is crucial for businesses as it ties up money until sold. Poor inventory management can lead to significant losses. A good inventory system helps in making decisions about what to stock and when to reorder.
Optimization methods
The review discusses methods for optimizing inventory costs. These include geometric programming, non-linear programming, and dual dynamic programming. Each method is applied to different demand patterns.
Review of articles
The review examines three articles on inventory systems. Each article uses a different optimization technique. The techniques are compared for their effectiveness in reducing inventory costs.
Genetic algorithms
Genetic algorithms are used to find the optimal targeted inventory. The process involves creating initial parent sets, crossover, and mutation. This method is compared with random search for its effectiveness.
Key terms
- Inventory
- Stocks of anything necessary to do business.
- Geometric programming
- A method to solve a particular type of non-linear problems.
- Dual dynamic programming
- A method that solves a linear program for each period parametrically.
- Genetic algorithm
- A method used to find the optimal targeted inventory.
- Marginal value curve
- A curve that shows the marginal value of inventory over time.
- Transportation cost
- The cost of moving inventory from one place to another.
