Given a set of service requests (events), a set of guided servers (units), and a set of unguided service contractors (conts), the vehicle dispatching problem VDP is the task to find an assignment of events to units and conts as well as tours for all units starting at their current positions and ending at their home positions (dispatch) such that the total cost of the dispatch is minimized. The ...

BACKGROUND Considerable development of MRI technology in diagnostic imaging, high cost of MRI technology and controversial issues concerning official charges (tariffs) have been the main motivations to define and implement this study. OBJECTIVES The present study aimed to calculate the unit-cost of MRI services using activity-based costing (ABC) as a modern cost accounting system and to fairl...

Cardiovascular conditions account for more medical costs than any other diagnostic category in the United States. Increasingly, economic constraints will shape policy related to health care and research. Hypertension is the most common cardiovascular condition, and despite low unit health care costs, the aggregate costs are considerable. However, the unit and aggregate costs of the complication...

this study presents a detailed analysis of cost management for intensive cultivation activity in terms of tomato production. the main objective was to provide qualitative and quantitative costs obtained in the intensive cultivation of tomato. this methodology was structured by activity costs (soil preparation and planting, crop monitoring, harvesting, selling, etc.) through a study in greenhous...

OBJECTIVES To identify and quantify resource required and associated costs for implementing TNF-α inhibitor (TNFi) drug level and anti-drug antibody (ADAb) tests in UK rheumatology practice. METHODS A microcosting study, assuming the UK National Health Service perspective, identified the direct medical costs associated with providing TNFi drug level and ADAb testing in clinical practice. Reso...

OBJECTIVE To calculate and compare costs of neonatal intensive care by micro-costing and gross-costing methods. METHODS The costs of resources of a tertiary care neonatal intensive care unit were estimated by the two methods to arrive at specific costs per diagnosis related categories for 33 neonates followed-up prospectively. RESULTS Gross-costing as compared to micro-costing resulted in h...

The assumption of expected profit-maximizing bidding behavior in a multi-unit, multi-period auction with step-function supply curves is used to estimate cost functions for electricity generation units and derive tests of expected profit-maximizing behavior. Applying these techniques to data from the National Electricity Market in Australia reveals statistically significant evidence of output-de...

We consider the single item lot-sizing problem with capacities that are non-decreasing over time. When the cost function is i) non-speculative or Wagner-Whitin (for instance, constant unit production costs and non-negative unit holding costs), and ii) the production set-up costs are non-increasing over time, it is known that the minimum cost lotsizing problem is polynomially solvable using dyna...

AIM To estimate hospitalisation costs for children with pertussis in New Zealand. METHOD All children less than 16 years of age and hospitalised with pertussis between 01/01/2003 and 31/12/2013 were identified from the National Minimum Data Set and the National Paediatric Intensive Care Unit database. The cost of hospital care was estimated by multiplying the diagnosis-related group cost-weig...
