A review: hybrid simulation in forestry supply chain

Changes in supply chain availability in the forestry sector can significantly change efficiency responsiveness. This forestry supply chain network involves various processes such as harvesting, energy generation, wood, paper and board production. Methods that can be used to perform supply chain optimization are hybrid modelling and simulation. Substructure techniques with experimental testing methods that target numerical component conductors with communication loop components as well as transfer systems to form an entire system commonly referred to as Hybrid Simulation. In this study, we aim to find solutions so that the supply chain network in the forestry sector is not cut off by using hybrid simulation method. Hybrid simulations used can take into account when the supply chain will run out and prevent excessive exploitation so as to repair damage and recycle the supply chain so that it is not disconnected until the time period is taken into account. Each scientific article is rigorously selected to obtain articles that align with the purpose of this research.


Introduction
The forestry sector plays an important role that greatly affects the industrial sector, namely as a supplier of raw materials used for the production process [1]. It can be seen how important the role of trees as the main materials of the paper making industry, the building materials industry of wood, rattan processing industry. Overtime, humans depend on natural resources that can only be obtained from forests so that the forestry sector greatly affects global conditions ranging from economic aspects to international development [2].
However, it is very important to pay attention to the availability of forestry resources called supply chain networks. Changes in supply chain availability can significantly change the response level of supply chain efficiency. The sustainability of supply chain networks in the forestry sector has received attention in recent years because resources are exploited to the point of depletion without regard to their impact on the environment so that the supply chain network is interrupted.
This research is focused on finding a solution so that the supply chain network in the forestry sector is not interrupted by using hybrid simulation which is a pseudo dynamic substructure testing method because hybrid simulation is a method that has a lot of potential but also has many challenges. This hybrid simulation is used to find solutions to keep the forestry supply chain sustainable.

Literature Review
Substructure techniques with experimental test methods by targeting connectors numerical components with communication loop components and transfer systems to form the entire system can be called Hybrid Simulations [3,4]. Certain types of hybrid simulation, for example, the hybrid model is based on two or more simulation models, the relationship between the model simulation and convenience or analysis models from a broader field of operation or discipline [5]. A supply chain is an organized chain to obtain raw materials, produce different products, and the results are distributed to consumers. One of the critical supply chain jolt is stock since changes in stock approach can radically alter the level of responsiveness and effectiveness of the supply chain [6]. An effective supply chain can be accomplished in case the administration and supervision of dispersion channel connections is carried out agreeably by all parties included. Paying attention to the form of supply chain regulation is very important.
The forest supply chain itself covers various stages and forms such as collection, transportation, the era of vitality, wood, paper, board production, and energy generation [7]. That means the forestry sector in addition to being a supplier of raw materials production processes in the industry can also be a source of energy raw materials that can reduce greenhouse gas emissions [8]. Forest supply chains are presently to a great extent characterized as discrete and detached substances that fulfill their trade exercises through exchanges [9]. Companies regularly work autonomously based on gauges taken from authentic information from clients of their coordinates that are at subordinate points to their downstream clients. This has prompted companies to function based on incorrect data, the well-known "bullwhip impact," coming in a variety of wasteful aspects and high work costs separately and collectively for the supply chain. Through collaborative arranging, request can be effectively satisfied from the closest forest supply range and wood transport can find the perfect course among all conceivable collaborative courses. For more details can be seen in the Table 1. The criteria for determining the mode of transportation of forestry results are indirect location of the letter and the nature of the disputed goods. However, the factors who determine variable are price, said, lead time, energy, and safety, as well as transportation that cannot be tightened [10].

Opportunities and Challenges in Forest Supply Chain Management in Argentina
Currently, the management of urban forestry management is passing through a paradigm, where the economic, social, environmental and logistical aspects are rather good. This screen is not the creation of supporters of what a strong and good decision. Despite its geography and increasingly accumulated climate, Argentina faces a major victory for the size of its natural villages, especially for forest production [20]. The results showed that both mechanisms can help the supply chain of timber forest products to achieve higher profits. The ERCS (Carbon Emission Reduction Cost-Sharing) mechanism is able to encourage producers to growth investment in technical emissions reductions and decrease overall carbon emissions, in addition to sell forestry corporations to enlarge woodland scale. The carbon sink fee sharing mechanism is useful for the expansion of carbon sink forests as nicely. but, it additionally leads to a huge increase inside the general carbon emissions of manufacturers, which produces terrible outcomes [21].
