Location Theory $5.00 Buy Now
A paper that presents a number of different location models for both the finite and discrete location models. Models include (1) the numeric-analytic model for the single facility infinite set location problem, (2) the Adaptive Allocation/Location model for the multiple facility infinite set location problem, (3) the Kepner-Tregoe Model for the finite set location problem, (4) the gravity model for finite set competitive store location problem, and (5) the p-median location problem.

Lotsizing $5.00 Buy Now
A paper that presents lotsizing models for both constant (time-invariant) and time-varying demand. For time-varying demand, the paper presents fixed order quantity (e.g., EOQ), time supply (Lot-for-lot, Period Order Quantity), and dynamic lotsizing (LTC, PPQ, LUC, LPC, WW) methods. The paper also discusses practical issues such as the models available in SAP and the importance of recognizing practical considerations such as the minimum order quantity, sequence-dependent setups, and shared setups.

Overall Equipment Effectiveness (OEE) $5.00 Buy Now
This paper explains the Overall Equipment Effectiveness (OEE) metric, which is considered by many to be a key tool for lean operations management. OEE is used extensively in Total Productivity Management (TPM) applications, particularly in large firms that have large capital intensive operations (e.g., 3M). This paper provides information on calculating OEE and provides a template (form) that can be used for this calculation. The paper also explains how to identify and manage the six big losses related to OEE, how to implement OEE, and how to avoid the dangers of OEE.

Price Optimization $5.00 Buy Now
This paper develops a model that can be used to find the optimal price to maximize profit. The model assumes that the price-demand model is exponential and that the user can supply two points on this curve (p1, D1) and (p2, D2). Calculus is used to find the optimal price. The companion Excel workbook by the same name implements the mathematics for this. This model ignores competitive response to a price change.

Queuing Theory $5.00 Buy Now
This paper presents a clear and simple summary of queuing theory intended for the undergraduate business or MBA student. The paper presents the M/M/1 model, the M/M/s model, and PK formula, and the approximate G/G/s model. A number of graphs and examples are used to make the concepts as clear and as simple as possible. A description of the advantages and disadvantages of pooling is presented. Emphasis is placed on the intuition that can be derived from queuing models.

Risk Management $5.00 Buy Now
This paper argues that risk management is a critical skill for all managers and should be used informally with smaller tasks and projects and formally with larger projects and initiatives. The best practice requires four steps: (1) identify potential adverse events, (2) propose risk mitigation projects, (3) prioritize risk mitigation projects, and (4) Execute risk mitigation projects. The paper argues further that project prioritization is better than the FMEA risk prioritization because some risks might be very expensive to mitigate, while others require little or nothing.

Safety Stock $5.00 Buy Now
This paper develops mathematical models for determining safety stock for independent demand inventory systems. After carefully defining terms, the paper develops a complete taxonomy of inventory management systems, and clearly defines the relationships between safety stock, reorder point, and order-up-to (target) inventory policy parameters. The paper presents four methods for calculating safety stocks: (1) the equal time safety stock method, (2) the order cycle service level method, (3) the unit fill rate service level method, and (4) the economic safety stock method. The paper argues against using the equal time method and then develops mathematical models for the other three methods. The paper presents models for handling a wide variety of demand during leadtime distributions, including the normal, gamma, Poisson, binomial, negative binomial, Erlang, and lognormal. The paper is intended for MBA readers who have some mathematical background.
