**3. DSS-OPILM and SisRot® LIX features**

The OPILM SisRot® LIX has been in development since 1989. Its scheme (**Figure 2**) presents the operational architecture of a set of computer systems that integrate through the web, allowing for optimized SWM (solid waste management)

and planning the different services to be performed. The system architecture is closely related to the conceptual DSS design model proposed by Klashner and Sabet [23] and the architecture proposed by Negreiros et al [24] and the web based framework developed to dengue control (webdengue) [25]. The core of the framework, corresponding to theory and analysis, includes the SARP system, which composes the algorithms for capacitated sectoring and routing, which are executed either manually or automatically. Heterogeneous sectoring is performed by heterogeneous capacitated centered clustering math heuristics, and the routing phase is performed with the mixed rural postman and movement prohibition reduction methods. These algorithms are executed according to the application (residential or selective domiciliary collection or human/mechanical street sweeping). The sectors and routes are part of the process final decision, and they are visualized through multigraph diagrams with movement/load/time/distance descriptions, multi-scaled vector maps (in different file formats), and street-by-street descriptive spreadsheets (in the XLS file format).

To better understand the OPILM in the portion of the SisRot®LIX, as shown above in **Figure 2**, a set of computational resources and parameters that govern the operational conditions in the field are necessary, as listed below:


Some characteristics of the solutions:

There is other arc routing software available in the market like TRANSCAD® [3]) and RouteSmart® [26] (from RouteSmart TechnologiesTM). As can be seen in Environmental Expert site [27], there are many other platforms for waste management, analysis, monitoring, and planning using sensors (Smart sensors, watchdog, RFID tags, smart button) using specific modules for asset management, waste monitoring, route planning and fleet management from SensoneoTM [28], and route planning from EasyRouteTM [29]. This late software are not arc routing based, they were built to accomplish point-to-point bins in domiciliary waste removal.
