A computerized reservations and scheduling system is provided which alternately allows transportation consumers to select from pre-scheduled transportation services provided by transportation providers or to negotiate and contract with transportation providers who have available unscheduled transportation space. The system comprises a central computerized data base. Transportation providers and consumers alike access the computer via a plurality of terminal units. The central computerized data base comprises a “maybe” file for storing information regarding available unscheduled transportation space which may be offered by a provider for service if a suitable consumer demand exists and for storing information regarding unscheduled transportation space which is needed by consumers. The “maybe” file facilitates negotiating and contracting between the parties.

It presents user-friendly features that will familiarize CITHM students on the online hotel reservation system, evaluate it and highlight the benefits it can provide to the college and staff. In addition, it will purvey supplement material in their front desk operation course. The researchers used the System Development Life Cycle and Microsoft Web Developer 2008 as the programming language. The developed software served as a tool for the students of CITHM to familiarize them on how to operate an online hotel reservation system. The developed software was an effective aid for the instructors in teaching the basic operations of hotel reservation system to their students. And these portrays that these is good reservation system where it is a user friendly one and it can also not hindrance for user to use in such way that they can easily access or to use the system that we made. It also provided online security to protect privacy and financial information of clients. BY: GLENDA ACORDA DELIZO and MISCHELLE ASI ESGUERRA

The central thesis of this dissertation is that by combining classical scheduling methodologies with those of inventory management and queuing theory we can better model, understand and solve complex real-world scheduling problems.
We provide models of a realistic supply chain scheduling problem that capture both its combinatorial nature and its dependence on inventory availability. We present an extensive empirical evaluation of how well implementations of these models in commercially available software solve the problem. We are therefore able to address, within a specific problem, the need for scheduling to take into account related decision-making processes.
We propose to integrate queuing theory and deterministic scheduling. Firstly, by reviewing the queuing theory literature that deals with dynamic resource allocation and sequencing and outlining numerous future work directions, we build a strong foundation for the investigation of the integration of queuing theory and scheduling. Subsequently, we demonstrate that integration can take place on three levels: conceptual, theoretical and algorithmic. At the conceptual level, we combine concepts, ideas and problem settings from the two areas, showing that such combinations provide insights into the trade-off between long-run and short-run objectives. Next, we show that theoretical integration of queuing and scheduling can lead to long-run performance guarantees for scheduling algorithms that have previously been proved only for queuing policies.
In particular, we are the first to prove, in two flow shop environments, the stability of a scheduling method that is based on the traditional scheduling literature and utilizes processing time information to make sequencing decisions. Finally, to address the algorithmic level of integration, we present, in an extensive future work chapter, one general approach for creating hybrid queuing/scheduling algorithms. To our knowledge, this dissertation is the first work that builds a framework for integrating queuing theory and scheduling. Motivated by characteristics of real problems, this dissertation takes a step toward extending scheduling research beyond traditional assumptions and addressing more realistic scheduling problems.
Integrating combinatorial scheduling with inventory management and queueing By: Daria Terekhov
Every management problem is a decision problem. Decision is an important task that all organizations have to take. The allocation of resource is a common issue to all organizations. Organizations have to acquire, allocate and control the factors of production which are necessary for the achievement of the business’s objectives. Inventory management as one of the key activities of business logistics, has always been a major preoccupation for the company’s survival and growth.
The aim of inventory management is to hold inventories at the lowest possible cost, given the objectives to ensure uninterrupted supplies for ongoing operations. When making decisions on inventory, management has to find a compromise between the different cost components, such as the costs of supplying inventory, inventory-holding costs and costs resulting from insufficient inventories (Hugo, Baden horst-Weiss and Van Rooyen 2002:169).
According to Wild (2002:4), inventory control is the activity which organizes the availability of items to the customers. It coordinates the purchasing, manufacturing and distribution functions to meet the marketing needs. This role includes the supply of current sales items, new products, consumables; spare parts, obsolescent items and all other supplies. Inventory enables a company to support the customer service, logistic or manufacturing activities in situations where purchasing or manufacturing of the items is not able to satisfy the demand. Lack of satisfaction could arise either because of the speed of purchasing or manufacturing is too protracted, or because quantities cannot be provided without stocks. Clodfelter (2003:279) adds that a good inventory control system offers the following benefits:
a. The proper relationship between sales and inventory can better be well maintained. Without inventory control procedures in place, the store or department can become overstocked or under stocked.
b. Inventory control systems provide a business with information needed to take markdowns by identifying slow-selling merchandise. Discovering such items early in the season will allow a business to reduce prices or make a change in marketing strategy before consumer demand completely disappears.
c. Merchandise control systems allow buyers to identify best-sellers early enough in the season so that re-orders can be placed to increase total sales for the store or department.
d. Merchandise shortages and shrinkage, can be identified using inventory control systems. Excessive shrinkage will indicate that more effective merchandising controls need to be implemented to reduce employee theft or shoplifting.
Design-to-time real-time scheduling is an approach to solving time-sensitive problems where multiple solution methods are available for many sub problems. The design-to-time approach involves designing a solution plan (i.e., an ordered schedule of solution methods) dynamically at runtime such that the solution plan uses the time available as productively as possible to try to maximize solution quality. The problem to be solved is modeled as a set of interrelated computational tasks, with alternative ways of accomplishing the overall task. There is not a single “right” answer, but a range of possible solution plans of different qualities, where the overall quality of a problem solution is a function of the quality of individual subtasks.
The act of scheduling such pre-specified task structures that contain alternatives requires both deciding “what” to do and deciding “when” to do it. One major focus of our design-to-time work is on taking interactions among sub problems into account when building solution plans, both “hard” interactions that must be satisfied to find correct solutions (e.g., hard precedence constraints), and “soft” interactions that can improve (or hinder) performance. Another recent focus of our work has been on adding to the problem model the notion of uncertainty in the duration and quality of methods, and in the presence and power of soft interactions. Scheduling with uncertain information requires additions to the scheduling algorithm and the monitoring of method performance to allow dynamic reaction to unexpected situations.
