The increased amount of flights in airports has caused serious problems for passengers and airlines, and brings risks to the system of ground traffic. The sequencing of taxi management is responsible for coordinating the process of rolling the aircraft from gate to track, or conversely, depending on the procedure for takeoff or landing. In this paper, it presents an optimization solution of tax...

This chapter intends to give an overview of the literature on dynamic lot-sizing models and stochastic transshipment models. These two types of models are used as a basis for developing models with substitution in the following chapters. Section 2.1 contains a classification of models for dynamic lot-sizing / production planning, and selected models. In Sect. 2.2, we give a brief overview of av...

The hybrid metaheuristics algorithms (HMHAs) have gained a considerable attention for their capability to solve difficult problems in different fields of science. This chapter introduces some applications of HMHAs in solving inventory theory problems. Three basic inventory problems, joint replenishment EOQ problem, newsboy problem, and stochastic review problem, in certain and uncertain environ...

The focus of this work is to study the behaviors of varies queue managements, including RED (Random Early Detection), SRED (Stabilized-RED), and BLUE. The performance metrics of the comparison are queue size, the drop probability, and link utilization. The simulation is done using NS-2. The results of this work shows that different from the RED, SRED and BLUE, which use the available queue leng...

Most current management applications provide a rather low-level view of the managed systems, have limited operations automation, usually forcing the manager to work at MIB variable level. To solve these problems, an approach based on a hierarchy of management algorithms for the different abstraction layers is used in this paper to manage a company’s business processes. An example is described t...

future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. in order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. therefore, it is predictable that the location updating and paging procedures will produce a major part of signaling traffic in these networks. this pape...

Proper arrangement of facility layout is a key issue in management that influences efficiency and the profitability of the manufacturing systems. Parallel Row Ordering Problem (PROP) is a special case of facility layout problem and consists of looking for the best location of n facilities while similar facilities (facilities which has some characteristics in common) should be arranged in a row ...

Taco Bell Corporation has approximately 6,490 company-owned, licensed, and franchised locations in 50 states and a growing international market. Worldwide yearly sales are approximately $4.6 billion. In 1988, Taco Bell introduced six core-menu items for the reduced price of 59 cents and offered free drink refills. Taco Bell has since continued to change and innovate. Its new strategy meant rest...

The traditional Economic Order Quantity (EOQ) model ignores the physical limitations of distribution practices. Very often distribution centers (DC) have to deliver merchandize in manufacturer-specified packages, which can impose restrictions on the application of the economic order quantity. These manufacturer-specified packages, or ship-packs, include cases (e.g., cartons containing 24 or 48 ...
