👔 Professional garments 🛁 Linen & hygiene 🔄 Delivery + collection 🏭 Multi-sector 🗺️ Nationwide

The dual delivery + collection flow — Kalhyge's unique logistical complexity

🚚
Delivering the clean

Delivering washed, maintained, and prepared items to each customer — respecting contractual frequencies and each site's specific receiving hours

Same route / same driver
📦
Collecting the soiled

Picking up used linen for return to the laundry facility — volumes that vary with customer activity, managing bags and packaging specific to each customer type

⚠️ Before TourSolver — the 4 limitations of manual processes
Time-consuming, inflexible general-purpose tools struggling with the complexity of the dual flow
High planning times — several hours per cycle to build routes
🔀
Unforeseen events hard to factor in — absences, emergencies, and volume changes disrupt the entire schedule
💸
High logistics costs — unoptimized mileage, underused vehicles
👁️
Limited customer visibility — no real-time tracking of routes and deliveries

Transforming the planning process — from several hours to a few minutes

Before TourSolver Several hours
manual route building — general-purpose tools, lots of re-entry
With TourSolver A few minutes
automatic route generation — every constraint factored in from the start

The 4 concrete benefits since deployment

  1. 1
    Massive planning time savings — from several hours to a few minutes

    TourSolver's automatic route generation turns an activity that used to occupy entire teams for hours into a process taking just minutes. The algorithm simultaneously factors in contractual visit frequencies, volumes to deliver and collect, each customer's time windows, and vehicle capacity — with no need for the planner to manage every parameter by hand. The time freed up can be devoted to customer relations and managing unforeseen events.

  2. 2
    📏Optimized routes and reduced costs — fewer kilometers, less fuel

    By geographically optimizing the dual-flow routes, TourSolver reduces the number of kilometers driven by each driver. For Kalhyge, which runs dozens of routes daily across the country, this reduction represents significant savings in fuel and vehicle maintenance costs — a direct economic benefit that also translates into a smaller carbon footprint for the fleet.

  3. 3
    🔄Visibility and flexibility — unforeseen events factored in real time with no service disruption

    TourSolver lets Kalhyge quickly account for unforeseen events — a driver's absence, an exceptional customer, a volume change — and adjust routes without manually rebuilding the entire plan. Real-time visibility into route progress gives managers an instant view of the situation in the field and lets them act proactively rather than simply react to events.

  4. 4
    Stronger customer satisfaction — deadlines met, reliable service

    Optimized routes and better-managed unforeseen events translate directly into respecting contractual deadlines and greater service reliability. For Kalhyge's customers — hotels, restaurants, industrial companies — the consistency of the textile service is critical: a late delivery can mean employees without workwear or tables without linens. TourSolver guarantees the consistency and punctuality that underpin customer trust.

🌱
The environmental approach — TourSolver as a lever for cutting carbon emissions

Beyond the immediate operational gain, Kalhyge situates the TourSolver rollout within a broader continuous improvement and environmental commitment. By reducing kilometers driven, the solution directly helps lower the fleet's CO₂ emissions — a major issue for a company running hundreds of routes every day. Future developments of TourSolver will further integrate environmental regulatory constraints.
