Two-sided matching algorithms for dynamic labor markets

Compared with manual total knee arthroplasty, patients younger than 65 years undergoing robotic arm—assisted total knee arthroplasty experience fewer days in hospital, less utilization of services, and lower average total costs at 90 days. Objectives: Previous studies on Medicare populations have shown improved outcomes and decreased day episode-of-care costs with robotic arm—assisted total knee arthroplasty RATKA. The purpose of this study was to evaluate expenditures and utilization following RATKA in the population younger than 65 years. Study Design: This is a retrospective longitudinal analysis of a commercial claims data set. Propensity score matching was performed at Utilization and associated costs were analyzed for 90 days following the index procedure. Patients who utilized home health aides in the RATKA arm utilized significantly fewer home health days 5. Am J Manag Care. Recently, there has been a steady increase in the number of total knee arthroplasty TKA procedures worldwide.

We consider the problem of computing a maximum cardinality popular matching in G. It is known that popular matchings always exist in such an instance G , however the complexity of computing a maximum cardinality popular matching was not known so far. In this paper we give a simple characterization of popular matchings when preference lists are strict and a sufficient condition for a maximum cardinality popular matching.

Consumers constantly decide which products and services best satisfy their needs and desires. Producers correspondingly decide how best to configure their products and services, from amongst a wide array of choices.

The paper addresses a variant of the stable marriage problem that models a job recruitment problem in which applicants are strictly ordered by priority but their preference lists may have ties.

Each applicant has a weight and provides a preference list, which may contain ties Gardenfors, P.: Match making: assignments based on bilateral preferences​.

The assignment problem, a well-known variant of which is the problem of optimal staff distribution, has formerly been treated as a problem of linear optimization starting with numerical evaluations of the assignments. In this paper the assignment problem is regarded as a problem of social choice, where preference orders are used as the sole initial information. A formal definition of an assignment function is given and various conditions for such functions are suggested.

Some conditions are found to be incompatible. Several reasonable assignment functions are examined with respect to which conditions they fulfil. Finally, some problems, related to the assignment problem, are informally discussed. Authors: Peter Gardenfors Peter Gardenfors. Search Search. Volume 66, Issue 8 August Volume 66, Issue 7 July

Two-sided matching is a hot issue in the field of operation research and decision analysis. This paper reviews the typical two-sided matching models and their limitations in some specific contexts, and then puts forward a new decision model based on uncertain preference sequences. In this model, we first design a data processing method to get preference ordinal value in uncertain preference sequence, then compute the preference distance of each matching pair based on these certain preference ordinal values, set the optimal objectives as maximizing matching number and minimizing total sum of preference distances of all the matching pairs under the lowest threshold constraint of matching effect, and then solve it with branch-and-bound algorithm.

Meanwhile, we take two numeral cases as examples and analyze the different matching solutions with one-norm distance, two-norm distance, and positive-infinity-norm distance, respectively. We also compare our decision model with two other approaches, and summarize their characteristics on two-sided matching. Two-sided matching is an important research branch in the field of operation research and decision analysis, which has been applied into many aspects of engineering and economics, such as commerce trading [ 1 , 2 ], work assignment [ 3 , 4 ], and resource allocation [ 5 , 6 ].

In many actual two-sided matching cases, due to the difficulty of information acquisition and fuzziness of the information identification, it is much easier for a decision maker to acquire the preference sequence of each element than other kinds of information, such as the weight value of connection between two elements in two disjoint sides, so preference sequence usually may be the essential and even the only basis for decision making.

However, when the scale of data grows rapidly, on one hand, it is nearly impossible to collect the complete preference sequence and, on the other hand, two or more elements in the preference sequence cannot be distinguished which ranks higher or lower because they have the same preference degree for the preference subject.
