We study inventory control for rental operations in a closed-loop supply chain. In such a system (e.g., Netflix), customers create online queues in a service provider’s website to indicate the items that they would like to rent. Leveraging this advance demand information, we propose effective forecast models and formulate a multi-item inventory control problem. We prove that the (L,U) policy is...

With this corrigendum, the authors of Zenetos et al. (2022) wish to notify readers a small number omissions and corrections in updated inventory Mediterranean non-indigenous species (NIS), recently undertaken by them, amend total NIS reported until December 2021.

In this study, data from the satellite sensors TanDEM-X and Sentinel-2 were combined with national field inventory to predict forest above-ground biomass (AGB) stem volume (VOL) over a large area in Sweden. The sources evaluated both separately combination. study covers approximately 20,000,000 ha corresponds about 70% of Swedish area. was divided into tiles 2.5 × km2, which processed sequentia...

Remote sensing and GIS are complementary technologies that, when combined, enable improved monitoring, mapping, and management of forest resources (Franklin 2001). The information that supports forest management is stored primarily in the form of forest inventory databases within a GIS environment. A forest inventory is a survey of the location, composition, and distribution of forest resources...

Ants (Hymenoptera: Forimicidae) are exceedingly common in nature. They constitute a conspicuous part of the terrestrial animal biomass and also considered ecosystem engineers. Due to their key role natural habitats, they at basis any nature conservation policy. Thus, first step developing adequate management policies is build precise faunistic inventory. More than 16,000 valid ant species regis...

Abstract Biodiversity surveys may require the use of multiple types sampling gear to maximize efficiency species detections, yet few studies have investigated how optimally distribute effort among gear. In this study, we conducted eDNA metabarcoding and capture‐based (electrofishing, fyke netting, gillnetting, seining) sample fish richness in a large northern temperate lake. We evaluated succes...

Abstract The study aimed to determine the types of orchids from domestication in Samaenre Village, Mallawa District, Maros Regency which is included as one buffer areas Bantimurung Bulusaraung National Park. This type research a descriptive with purposive sampling method, only records maintained by community Regency. results showed that there were 26 orchids. 11 identified species level and 15 ...

In this paper, we propose a simple heuristic approach for the inventory control problem with stochastic demand and multiplicative random yield. Our heuristic tries to find the best candidate within a class of policies which are referred to in the literature as the linear inflation rule (LIR) policies. Our approach is computationally fast, easy to implement and intuitive to understand. Moreover,...
