Multiple Objective Analysis of Input-Output Models for Emergency Management
1990
This paper shows how a visual, interactive, dynamic multiple objective linear programming decision support system can effectively be used for analyzing input-output models. We have applied our approach to studying the quantitative effects of economic or political crises to the Finnish economy. Examples of such crises are nuclear power plant accidents, trade embargoes, and international conflicts. An input-output model of the Finnish economy with 17 industries (sectors) is employed. Our system has been implemented on a microcomputer and is being used by the National Board of Economic Defense. Several typical case situations are discussed.
A software for the integrated design of wastewater treatment plants
1998
Abstract A software package has been developed for automated design of wastewater treatment plants. A user-friendly environment has been implemented to facilitate design tasks, allowing rapid evaluation of different alternatives as well as performing sensitivity analyses. Flexible treatment plant configurations can be established with preliminary, primary, biological and tertiary wastewater treatments, and sludge treatment units. A generalized steady-state model developed for biological processes is also included. The design process includes treatment units sizing, plant layout, hydraulic profile calculation and equipment assignment. The system capabilities for designing new plants and upgr…
A global model for the estimation of transport costs
2019
This paper presents a model of transport cost determinants that corrects the specification problems observed in the transport cost equations in previous literature. The model includes freight transport supply and demand, as well as infrastructure quality and non-time-varying fixed effects related to the route, the exporting company, its strategy and the product. In addition, when defining the origin-destination routes, the model more appropriately accounts for economies of network and economies of scale. In order to build the database, 583 personal interviews were conducted over the course of 2011 with producing companies that ship goods and with the logistics operators. As a result, 305 ro…
A New Dynamic Model for Anticipatory Adaptive Control of Airline Seat Reservation via Order Statistics of Cumulative Customer Demand
2017
This paper deals with dynamic anticipatory adaptive control of airline seat reservation for the stochastic customer demand that occurs over time T before the flight is scheduled to depart. It is assumed that time T is divided into m periods, namely a full fare period and m−1 discounted fare periods. The fare structure is given. An airplane has a seat capacity of U. For the sake of simplicity, but without loss of generality, we consider (for illustration) the case of nonstop flight with two fare classes (business and economy). The proposed policies of the airline seat inventory control are based on the use of order statistics of cumulative customer demand, which have such properties as bivar…
Adaptive Stochastic Airline Seat Inventory Control under Parametric Uncertainty
2013
Airline seat inventory control is a very profitable tool in the airline industry. The problem of adaptive stochastic airline seat inventory control lies at the heart of airline revenue management. This problem concerns the allocation of the finite seat inventory to the stochastic customer demand that occurs over time before the flight is scheduled to depart. The objective is to find the right combination of customers of various fare classes on the flight such that revenue is maximized. In this paper, the static and dynamic policies of stochastic airline seat inventory control (airline booking) are developed under parametric uncertainty of underlying models, which are not necessarily alterna…
Customer Relationships Management in Organizations
2013
Abstract In recent years, the market for on-demand CRM applications suffered especially in the segment of small and medium companies because of the concerns about the cost and the complexity of on request implementations. CRM on demand is a good choice for companies that want to implement standard processes that can use data structures “out of box” with little or not at all internal IT support and does not require complex or real-time integration with back office systems. However, on-demand CRM software is not always as simple as vendors want us to believe. Customizing can be problematic and interface tools of CRM vendors can not provide desired levels of integration. Implementing a hosted …
Method to Define User Interfaces in the Requirements Analysis Phase
2018
Many requirements for quality in use are elicited in the late development phase. However, if requirements are elicited in the late development phase, the development may return to the previous phase or some requirements cannot be realized due to costs and schedules. To reduce these cases, we propose a method to elicit the requirements in the requirements analysis phase. First, software developers analyze the user characteristics (UCs) of the target users and specify important quality characteristics (QCs) for quality in use and UI design items based on the relationships among UC, QC, and UI design items. Because UI design items are considerations to develop UIs, the specified UI design item…
Using the modern CNC controllers capabilities for estimating the machining forces during the milling process
2017
Machining forces can nowadays be measured by using 3D dynamometers, which are usually very expensive devices and hardly available for most of the CNC machine-tools users. On the other hand, modern CNC controllers have nowadays the ability to display and save many outputs within the machining process, such as the currents or even the torques at the shaft's level for the feed motors on each axis. These outputs can be used for estimating the machining forces, but it is to be noticed that the above-mentioned currents and torques are proportional with the overall resistant forces, which includes not only technological forces, but also friction, inertial and pre-tensioning forces. This paper pres…
