OR Spectrum facilitates discussions on Mathematical optimization, Operations research, Operations management, Heuristics and Simulation. The journal explores issues in Mathematical optimization which can be linked to other research areas like Algorithm and Job shop scheduling. The journal explores the study of Job shop scheduling to improve our understanding of the broader topic of Scheduling (computing).
It facilitates discussions on Operations research that incorporate concepts from other fields like Production (economics), Scheduling (production processes) and Order (business). The study on Heuristics presented is investigated in conjunction with research in Heuristic.
The most cited publications investigate areas of study like Operations research, Mathematical optimization, Operations management, Simulation and Heuristics. Issues in Operations research were discussed in the published articles, taking into consideration concepts from other disciplines like Genetic algorithm, Emergency management, Key (cryptography), Order (business) and Integer programming. Most of the works presented in the published articles deal with Mathematical optimization but they intersect with the subject of Algorithm.
OR Spectrum covers a variety of subjects, including Mathematical optimization, Operations research, Data envelopment analysis, Integer programming and Process (engineering). The studies in Mathematical optimization featured incorporate elements of Series (mathematics) and Nonlinear system. The studies on Operations research discussed can also contribute to research in the domains of Context (language use), Inefficiency, Social planner, Ticket and Perfect competition.
While Integer programming is the key highlight in it, it also covered some subjects on Column generation and Materials management, Solver and Production planning. While work presented in it provided substantial information on Process (engineering), it also covered topics in Competition (economics), Stochastic game, Product (category theory), Game theory and Fixed cost. The journal holds forums on Heuristics that merges themes from other disciplines such as Truck and Limit (mathematics).
A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.
The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.
The top authors publishing in OR Spectrum (based on the number of publications) are:
The overall trend for top authors publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top authors.
Only papers with recognized affiliations are considered
The top affiliations publishing in OR Spectrum (based on the number of publications) are:
The overall trend for top affiliations publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top affiliations.
The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.
The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.
During the most recent 2021 edition, 4.17% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 15.22% were posted by at least one author from the top 10 institutions publishing in the journal. Another 10.87% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 10.87% of all publications and 63.04% were from other institutions.
A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.
The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.
The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.
Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).
The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:
The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
