“…Moving from the current solution to the neighbouring solution continues until the end condition of the algorithm is met. Different termination conditions can be considered for the algorithm, for example, the limit of the number of moves to the solution can be a termination condition (Brown and Affum, 2002;SHIRAVAND et al, 2020). The flowchart of the tabu search algorithm is shown in Figure 4.…”

Abstract. Finding the desired products and achieving them at the lowest possible cost has always been one of the concerns of in-person buyers. Finding stores containing the desired products is one of the most important services that can be provided to this part of the buyer community. It provided that the costs are minimal, as well as determining the order of visiting the stores and guiding the buyer by routing between store and buyer positions. Transportation is also one of the most important applications of spatial information systems in the field of optimal management of facilities. In this study, routing was performed by Algorithm A*, which was slightly different from the Dijkstra algorithm in terms of accuracy, but in terms of response time, recorded an average reduction of 70%.

“…The catchment area is 2481 square km and its perimeter is 702 km. Khorramabad has a relatively large canal that drains flood waters caused by rainfall and eventually leads to the Karkheh Dam (Khaledi and Behzadi, 2020;Shiravand et al, 2019). This canal, which passes through the center of Khorramabad, has a sub-branch called the Karganeh Canal.…”

Today, there are varieties of methods for determining the risk of flooding in different areas of a catchment. However, the use of GIS-based weighting is receiving increasing attention among researchers. In early 2019, severe and continuous floods occurred in some provinces of Iran. Khorramabad was one of the cities most affected by the floods. Regrettably, during the construction development of Khorramabad city, the minimum distance from roads was violated. In this study, flood risks in the area were zoned using a GIS-weighted overlay algorithm. Flood zoning was done based on various maps indicating factors such as rainfall, distance from the waterway, soil composition, waterway density, slope, soil permeability, land use, and vegetation. The flooding area then was parceled into six categories with return periods of 10, 30, and 50 years. As a result, the city was divided into three critical areas in terms of flood risk. The results indicate that the confluence of the Karganeh and Khorram–Rud rivers lacks sufficient capacity to withstand and repel floods. As a result, the city will suffer severe damage in future floods.

“…Badehian et al 52 reported oak decline in Lorestan province changed the number of secondary compounds, e.g., total tannin and insoluble sugar in leaves of Presian oak ( Quercus brantii ). Shiravand et al 66 showed that from 2000 to 2017, more than 1.7% (42,802 hectares) of oak forests of Lorestan province completely declined.…”

The Zagros oak forests in Iran are facing a concerning decline due to prolonged and severe drought conditions over several decades, compounded by the simultaneous impact of temperature on oak populations. This study in oak woodlands of central Zagros forests in Lorestan province analyzed abiotic factors such as climate properties, topographic features, land use, and soil properties from 1958 to 2022. We found that higher elevation areas with steeper slopes and diverse topography show significant potential for enhancing oak tree resilience in the face of climate change. Additionally, traditional land use practices like livestock keeping and dryland farming contribute to a widespread decline in oak populations. Preserving forest biodiversity and ensuring ecological sustainability requires immediate attention. Implementing effective land-use management strategies, such as protecting and regulating human-forest interaction, and considering meteorological factors to address this issue is crucial. Collaborative efforts from stakeholders, policymakers, and local communities are essential to oppose destructive suburban sprawl and other developments. Sustainable forestry practices should be implemented to improve the living standards of local communities that rely on forests and traditional livestock keeping, offer forestry-related jobs, and ensure social security. Such efforts are necessary to promote conservation awareness and sustainable practices, safeguarding this unique and vital ecosystem for future generations.
