Dynamic Allocation Of Airline Check-In Counters: A Queueing Optimisation Approach, Mahmut Parlar, Sharafali Moosa

Research Collection Lee Kong Chian School Of Business

This paper was motivated by an observation in an international airport with regard to allocation of resources for check-in counters. In an exclusive check-in counter system, each flight has a dedicated number of counters that will be open until at least a half-hour before the scheduled departure of that flight. Currently, in many of the airports around the world, the decision to open or close check-in counters is done on an ad hoc basis by human schedulers. In doing so, the schedulers are almost always forced to perform a balancing act in meeting the quality of service stipulated by the …

Measuring Agility Of Organizations - A Comprehensive Agility Measurement Tool (Camt), Ameya S. Erande, Alok K. Verma

Engineering Technology Faculty Publications

Since "Agility" is ability to respond to unpredictable changes with quick response and profitability, it is not industry specific. This "not industry specific" nature of agility makes it hard to assess and measure it on a fixed scale. Measurement of agility of an enterprise has been a major topic of research since inception of agility in 1991. Though some methods have been developed to measure agility, they mainly remain tied to manufacturing industry. As agility is present in all the industries, comprehensive tool to measure it is a necessity in order to determine responsiveness of an enterprise to external turbulences. …

Fisheries Research Contract Reports

The use of scientifically based hazard identification, risk analysis and risk management is fundamental to managing unwanted effects. Hazards, such as quarantine incursions, will continue to occur despite the use of risk assessment methodologies but the frequency and severity of their occurrence will be reduced.

This was recognised by the Ministerial Council on Forestry, Fisheries and Aquaculture in 1999 when they published the "National policy for the translocation of live aquatic organisms".

This FRDC project provides a simple risk assessment methodology based on the Australian Standard for Risk Management (AS/NZS 4360: 2004) and one that is consistent with the Ministerial …

An Adaptive Tabu Search Heuristic For The Location Routing Pickup And Delivery Problem With Time Windows With A Theater Distribution Application, Robert E. Burks Jr.

Theses and Dissertations

The time constrained pickup and delivery problem (PDPTW) is a problem of finding a set of routes for a fleet of vehicles in order to satisfy a set of transportation requests. Each request represents a user-specified pickup and delivery location. The PDPTW may be used to model many problems in logistics and public transportation. The location routing problem (LRP) is an extension of the vehicle routing problem where the solution identifies the optimal location of the depots and provides the vehicle schedules and distribution routes. This dissertation seeks to blend the PDPTW and LRP areas of research and formulate a …

Modeling A Reparable Supply Chain And Applying Cpfr Concepts, Sandra A. Mayhall

Theses and Dissertations

The Air Force supply chain includes parts required to build, fix, or maintain aircraft delivered to the warfighter to carry out missions. Industry has shown that following Collaborative Planning, Forecasting, and Replenishment (CPFR) concepts, particularly reducing inventory through accurate demand forecasts, has increased profits in part by lowering the holding costs of inventory and increasing sales. This is analogous to the Air Force increasing aircraft availability. There is scant evidence that demand forecasts generated at any level in the Air Force are shared with the intent of coordinating replenishment. This thesis uses a simple discrete-event stochastic simulation model to show …

Logistics Network Design With Differentiated Delivery Lead Time: A Chemical Industry Case Study, Michelle Lee Fong Cheong, Rohit Bhatnagar, Stephen C. Graves

Research Collection School Of Computing and Information Systems

Most logistics network design models assume exogenous customer demand that is independent of the service time or level. This paper examines the benefits of segmenting demand according to lead-time sensitivity of customers. To capture lead-time sensitivity in the network design model, we use a facility grouping method to ensure that the different demand classes are satisfied on time. In addition, we perform a series of computational experiments to develop a set of managerial insights for the network design decision making process.

Vehicle Routing For Milk Procurement, Janat Shah

IIMB Management Review

In a typical co-operative dairy, one of the significant operating costsunder the control of the management is the cost of milk collectionand transportation. (Exhibit 1 shows the typical cost structure of adairy) The dairy under study picked up milk from 500-800 pick uppoints (nodes) twice a day. The vehicle routes were decided manu-ally keeping in mind the peak load expected at the nodes during thecoming year. The dairy had about 50 odd routes, each route cover-ing an average of 15 nodes. Usually dairies do not own the ve-hicles but use transport contractors who enter into an annual con tract with …

Product-Mix Optimiser For An Integrated Steel Plant, Goutam Dutta, Gopal P Singh, P N Roy

IIMB Management Review

Optimal utilisation of constrained resources is one of the most important problems in the area of operations management. The determination of optimal productmix is an extremely difficult task for an organisation producing multiple products in multiple stages, sharing a set of common plant resources and experiencing a fluctuating market over time. In the absence of a quick method to determine optimality under changing conditions, plant managers have to make decisions based on their experience and intuition. 

The Pilgrim's Progress: Operations Research In Queuing, G Raghuram

IIMB Management Review

Good management practice is synonymous with applying operations research (OR). Both imply a systematic approach beginning with clarity in problem definition, understanding the objectives and constraints, characterising the alternatives (these three steps constitute  model building), evaluating (analysing) them and finally selecting an alternative for implementation. In addition to this basic methodology, there is also an implication of a quantitative basis to the extent possible. It is this quantitative basis which lends to the common perception that good management practice is much larger than OR

A Combined Inventory And Delivery Model For Repairable Items, Bahtiyar Eren

Theses and Dissertations

Traditionally, logistics analysts have treated the delivery problem separate from the inventory and repair problems. In other words, each of these three problems-delivery, inventory, and repair-are treated individually. We combine the vehicle routing problems and inventory allocation problems in a single formulation. Furthermore, lateral re-supply is considered, in that supplies are not only available from the main depot, but also from other bases. After we get the lateral re-supply information, we set a delivery allocation plan out of the main depot. Such allocations are then delivered via vehicles stationed at the main depot. There is a repair capability for each …

Theses and Dissertations

Air Mobility Command (AMC) uses the Airlift Flow Model as their primary tool to estimate the amount of cargo delivered in a Time Phase Force Deployment Document (TPFDD). The primary objective of this research was an exploratory investigation in the development of a metamodel to predict the amount of cargo delivered from a TPFDD by AMC into a theater. In creating a valid metamodel the analyst would be able to quickly provide the decision-maker with accurate insights should input parameters change. This would save valuable time and replace the need to physically change the input parameters and re-run the simulation. …

The Distributor’S Three-Dimensional Pallet-Packing Problem: A Mathematical Formulation And Heuristic Solution Approach, Brian P. Ballew

Theses and Dissertations

It is through practice and experience Air Force loadmasters are able to pack the Air Force standard HCU-6/E (463L) pallets efficiently. Although the loadmasters perform their jobs exceptionally well, the Air Force is in search of a model that will more efficiently pack the pallets. We have developed a mathematical formulation of the three-dimensional pallet-packing problem which minimizes the amount of unused space on a pallet. The formulation ensures each box is packed with the correct volume and dimensions, and ensures the volume of all the boxes packed is less than the available pallet volume. Additionally, the formulation ensures that …
