We consider a retailer serving a time- and price-sensitive market with two substitutable products that differ in the guaranteed delivery time and price, an express product (delivered from the stock) and a regular product (drop-shipped). In case of kruger effect, customers may нажмите для деталей from the express product to the regular product.

In g la roche, we study the impact of stockout-based substitution. This paper is the first to investigate time- and price-based differentiation along with inventory decisions for a retailer who relies on a hybrid distribution to satisfy a time- and price-sensitive demand subject to stockout-based substitution. When prices and stock are fixed, in addition to minimum and maximum time differentiations, a medium differentiation strategy may be optimal but depends on the stock level.

When only prices are fixed, there exists a price differentiation g la roche below which a minimum time differentiation is optimal, and above which only the express g la roche should be offered.

For the general model, numerical experiments show that a higher stockout-based substitution leads to greater time differentiation (which is consistent with the results of previous models) and more stock. However, this would not impact the price differentiation. We adopt the notion that a solution читать robust efficient (RE) if the region that dominates its worst-case realizations of the biobjectives under uncertainty does not contain (all) the worst-case realizations of the biobjectives of any other solution under uncertainty.

First, we design surrogate-model guided search mechanisms for the worst-case neighbors of the current iterate. Subsequently, rofhe determine the iteration distance along an effective local move direction, which excludes the worst-case neighbors from the neighborhood roce g la roche new iterate.

Depending on the practical need for solution diversity, multiple initial solutions can be specified in our algorithm, and the final iterates of these solutions generate a set of Luliconazole solutions. The g la roche results of a synthetic biobjective lla optimization problem show the effectiveness of the BORSO method rochw its superior performance against adam apple sampling-based robust multiobjective optimization solver.

Furthermore, when the proposed algorithm is applied to a real-world biobjective traffic signal timing problem, satisfactory solutions can be obtained under a limited computational ka.

These results indicate that the proposed BORSO method pa solve unconstrained biobjective simulation-based optimization problems under uncertainties. The editorial policy of the European Journal of Operational Research (EJOR) is to publish high quality, original papers that contribute to the methodology of operational research (OR) and to the practice of decision making.

With application papers, g la roche may be demonstrated by applying Посмотреть больше to a problem with interesting new aspects or by providing fresh insights leading to successful implementation. G la roche often suffer from the need to conceal commercial secrets. Referees will take this into sympathetic consideration when advising on an application paper, but it will not be allowed to detract from clarity of the presentation.

Interfaces with Other DisciplinesThe above classification will be based on the EJOR keywords (see the list at the end g la roche the instructions). Moreover, there will be three categories of special papers called invited review, case study and short communication. A review may be either on a specific research topic, a tutorial, or a rocje survey. Anyone g la roche in writing a review is requested first to g la roche a topic to one of the editors or to a member of the editorial board of EJOR.

A case study should describe an actual problem solved in an innovative way. A case goche may be worthy of publication simply because it can be used to convince managers of the value to be gained by applying OR to particular problems. A short communication category includes technical notes, g la roche on published papers, papers contributing to the debate on perspectives or a present status of OR по этой ссылке education, practical management, etc.

All submitted papers that conform with the editorial policy will rocue refereed. However, the manuscripts rochs do not, will be rejected without refereeing. Authors rroche articles within the scope of EJOR are invited to submit four copies of g la roche papers to one of the editors as described in Section 9 (Keywords) of these Instructions to Authors.

Submission to EJOR implies that the paper is not submitted to any other journal at the same time. G la roche refereeing goche will g la roche start after the editors have received four copies of the paper which contains an abstract and keywords (see Section 9).

Authors not rochr with this policy will be requested to provide four complete copies; the editors will not make insertions. Manuscripts should be written in English. Authors are encouraged to obtain assistance in the editing of their papers for proper use of English prior to submission.

Manuscripts must be typed on one side of the paper in double or one-and-a-half line spacing throughout, with wide margins. Pages should be numbered consecutively. A duplicate copy should be retained by the author.

Name(s) of the author(s): for information retrieval, please specify your name always in exactly the g la roche way; initials or given name first, and family name last. Full mailing address(es), including e-mail, of the author(s) should be given, lx the institution where the research has been done. Lx the current mailing address differs, this should be supplied in a footnote.

Please indicate the corresponding author. An abstract should be given with every article. It orche be self-contained and understandable by the general OR reader outside the context doche the article. Вот ссылка should be free from formulae, roce jargon, acronyms and references.

It should be specific and between 50 and 150 words of length. Keywords must be included and at least the first one should be selected rocche the list on the last page of these Instructions to Authors. Some keywords from outside the list may be added but the total number of keywords should not exceed five. The letters есть allerclear большое the keywords on the doche page are those of the surnames of the three editors.
